FDMSReversal Control

Properties Methods Events Config Settings Errors

The FDMSREVERSAL control is used to reverse a transaction that was previously authorized using the FDMSRETAIL , FDMSECOMMERCE , or FDMSHEALTHCARE control. This immediately releases the funds in the cardholder's open-to-buy that were blocked by the original authorization.

Syntax

FDMSReversal

Remarks

Unlike the Timeout Reversals used in the FDMSDebit and FDMSBenefit controls, a credit card reversal is used to void a transaction and return funds to the customer. Often this is used in a split-tender situation, where a customer uses a prepaid Visa or MasterCard (or health care FSA card) to make a purchase which is partially authorized for less than the transaction amount. Partially authorized transactions will have an ResponseApprovalCode that beings with "AL" instead of "AP". If the customer does not have an additional source of funds to make up the difference, the authorization must be reversed and the funds immediately returned to the customer's card. To do this, set the AuthorizedAmount to the Response.AuthorizedAmount from the original transaction, and set the SettlementAmount to "0". This is called a full reversal (in this case, of a partially authorized transaction), and the detail record for the original transaction should be discarded - it must not be settled at the end of the day.

Alternatively, a merchant may need to settle a transaction amount for less than was originally authorized. In this case, set the AuthorizedAmount to the original TransactionAmount, and set the SettlementAmount to the new amount you wish to settle for. After a successful reversal, use the FDMSDetailRecord control to update the SettlementAmount of the detail record for the original transaction with the new amount. This is called a partial reversal. You may also submit a full reversal by setting the SettlementAmount to "0". In that case, all of the funds are returned to the customer and the detail record for the original transaction should be discarded.

Note that partial authorizations must be fully reversed. You cannot partially reverse a partial authorization. Normally authorized transactions can be either partially or fully reversed. A normal authorization has a ResponseApprovalCode that begins with "AP" (APproved). A partial authorization has a ResponseApprovalCode that begins with "AL" (Approved for a Lesser amount).

Upon a successful reversal, the ResponseApprovalCode property will contain either "AP888888" or "AP868686" indicating the reversal was accepted. This code does not indicate the original transaction was found and reversed, merely that the reversal was received and properly formatted. First Data does not actually check whether the original transaction occurred or not. If the transaction was declined ResponseApprovalCode will contain one of the response messages listed in the table below:


Response Message	Meaning
CALL CARD CENTER	System problem.
DECLINED	Decline the transaction.
EXPIRED CARD	Card is expired.
HOLD - CALL CTR	Problem with card.
INV ACCT NUM	Invalid card number or prefix.
INV CREDIT PLAN	Private label message only.
INV EXP DATE	Invalid expiration date.
INV MER ID	Merchant is not set up on Host file.
INV TERM ID	Terminal is not set up on Host file.
PLEASE RETRY	System time-out or other generic system error.
REFERRAL	Referral.
REFERRAL INV TR2	Referral - Invalid Track II Data.
REFERRAL INV TR1	Referral - Invalid Track I Data.
SERV NOT ALLOWED	Merchant is not entitled to this card type.
SYS REJECT	Transaction was rejected by the system due to "batch in progress indicators" being turned on.
INV AMT	Invalid amount.
INV TRAN	Transaction not permitted
REV REJECTED	Reversal was rejected.
TRAN NOT ALLOWED	Transaction not allowed.

The following example starts with a simple $3 manually-keyed retail transaction:

  
  FDMSRetail1.TransactionNumber = 3;
  FDMSRetail1.TransactionAmount = "300";
  FDMSRetail1.Card.Number = "4111111111111111";
  FDMSRetail1.Card.ExpMonth = 12;
  FDMSRetail1.Card.ExpYear = 13;
  FDMSRetail1.Card.EntryDataSource = edsManuallyEntered;
  FDMSRetail1.Authorize();

The above authorization was successful, but for some reason it needs to be voided. You could simply not settle the transaction, and that would clear the block on the cardholder's funds in a few days. However, a reversal allows you to clear that block immediately. To start with, we set the FDMSReversal control with the same merchant setup and basic transaction info used in the original authorization.

 
  FDMSReversal1.MerchantNumber         = FDMSRetail1.MerchantNumber;
  FDMSReversal1.MerchantTerminalNumber = FDMSRetail1.MerchantTerminalNumber;
  FDMSReversal1.DatawireId             = FDMSRetail1.DatawireId;
  FDMSReversal1.URL                    = FDMSRetail1.URL;
  FDMSReversal1.Card.Number            = FDMSRetail1.Card.Number;
  FDMSReversal1.Card.ExpMonth          = FDMSRetail1.Card.ExpMonth;
  FDMSReversal1.Card.ExpYear           = FDMSRetail1.Card.ExpYear;
  FDMSReversal1.Card.EntryDataSource   = FDMSRetail1.Card.EntryDataSource;

Next, we need to specify the exact transaction we wish to reverse. The properties below are required for First Data to identify and reconcile the reversal. Note that if the original transaction was authorized for an amount less than the original TransactionAmount, AuthorizedAmount should be set with the ResponseAuthorizedAmount from the original transaction, instead of the TransactionAmount which was requested.

  FDMSReversal1.ApprovalCode     = FDMSRetail1.Response.ApprovalCode;
  FDMSReversal1.TransactionId    = FDMSRetail1.Response.TransactionId;
  FDMSReversal1.AuthorizedAmount = FDMSRetail1.TransactionAmount;
  FDMSReversal1.ReturnedACI      = FDMSRetail1.Response.ReturnedACI;
  FDMSReversal1.ValidationCode   = FDMSRetail1.Response.ValidationCode;

All that is left is to set the new settlement amount and submit the transaction. To completely reverse the transaction and return all funds to the customer, set the SettlementAmount to zero ("0"). To return a portion of the funds to the customer set the SettlementAmount property with the result of the original authorized amount minus the amount to be unblocked on the customer's card. For instance, this $3 transaction has $2 reversed, for a new settlement amount of $1.

  FDMSReversal1.TransactionNumber = 4;
  FDMSReversal1.SettlementAmount  = "100";
  FDMSReversal1.Reverse();

If the reversal is successful the ResponseApprovalCode will contain either "AP868686" or "AP888888", indicating the reversal was accepted.

Note that partially authorized transactions cannot be partially reversed, they must be fully reversed. For instance, say a customer uses a prepaid visa card to buy $100 worth of merchandise, but his card only has a $50 balance. If the customer does not have an additional form of tender, (cash, check, credit, etc), the $50 that was partially authorized must be reversed and returned to the card. First Data does not support any scenario where a partially authorized transaction may be reversed for less than the full amount.

To reiterate, when a transaction is fully reversed, it must be removed from the batch settlement entirely. A partially reversed transaction must update the SettlementAmount of the original detail record, using the FDMSDetailRecord control. Reversal transactions themselves may not be settled, even if the ResponseCaptureFlag is True.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister control. (You may update your list of service provider URLs with the FDMSRegister control's ServiceDiscovery method).

ApplicationId Property (FDMSReversal Control)

Identifies the merchant application to the Datawire System.

Syntax

fdmsreversalcontrol.ApplicationId[=string]

Default Value

"NSOFTDIRECTPXML"

Remarks

The Application ID includes the Merchant's application name and version number. This property is used to identify the merchant application within the Datawire system, and may be validated along with the MerchantTerminalNumber and DatawireId as connection credentials.

The default value of this property is assigned to the 4D Payments FDMS Integrator, but you may be required to have a new ApplicationId assigned for the software you create with this control.

Data Type

String

ApprovalCode Property (FDMSReversal Control)

Approval code of the transaction to be reversed.

Syntax

fdmsreversalcontrol.ApprovalCode[=string]

Default Value

Remarks

This property should be set with the Response.ApprovalCode from the transaction you wish to reverse.

Data Type

String

AuthorizedAmount Property (FDMSReversal Control)

Authorized Amount from the original response.

Syntax

fdmsreversalcontrol.AuthorizedAmount[=string]

Default Value

Remarks

This property should be set with the actual authorized amount from the transaction you wish to reverse. If the transaction was partially authorized (Response.AuthorizedAmount was present in the response, and different than the original TransactionAmount), then this property should be set to the AuthorizedAmount returned in the original response. Otherwise it should be set to the original TransactionAmount.

If the original transaction was partially authorized, you cannot do a partial reversal. Partially authorized transactions must be fully reversed (meaning SettlementAmount must be set to "0").

In the case of reversing a transaction containing incremental authorizations, this property should be set to the first (initial) authorization amount. The TotalAuthorizedAmount config should then be set to the total authorization amount (first authorization plus all incremental authorizations).

Data Type

This alphanumeric property contains the three digit Visa "Card Verification Value" (CVV), MasterCard "Card Verification Code" (CVC), or four-digit American Express "Card Identification Number" (CID). This value appears as additional characters embossed on the card signature line following the credit card account number on the back of the credit card. This is an optional property which can be used to determine if the customer is actually in possession of the credit card.

Even if the CardCVVData is incorrect, the transaction may still be authorized. It is up to the merchant to examine the ResponseCVVResult property and decide whether to honor the transaction or not.

Note: When set to a non-empty value, CardCVVPresence will be automatically set to cvpProvided. If set to empty string (""), CardCVVPresence will be automatically set to cvpNotProvided.

CardIsEncrypted Property (FDMSReversal Control)

Determines whether data set to the Number or MagneticStripe properties is validated.

Syntax

fdmsreversalcontrol.CardIsEncrypted[=boolean]

Default Value

False

Remarks

Determines whether data set to the CardNumber or CardMagneticStripe fields is validated.

By default, when the CardNumber or CardMagneticStripe fields are set, the value will be validated and normalized. For instance, "4444-33332222 1111" will be normalized as "4444333322221111" and CardMagneticStripe data will be parsed for the track specified by CardEntryDataSource. However, any other non-numerical data entered will cause an exception to be thrown. It may be useful in some gateways to send other data in the CardNumber or CardMagneticStripe fields, and this can be accomplished by setting IsEncrypted to true. However, please note that in doing so automatic calculation of the CardType may be affected, and the card number will not be verified.

This property is not available at design time.

Data Type

Boolean

CardMagneticStripe Property (FDMSReversal Control)

Track data read off of the card's magnetic stripe.

Syntax

fdmsreversalcontrol.CardMagneticStripe[=string]

99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Data Type

Integer

SSLCertSubject Property (FDMSReversal Control)

This is the subject of the certificate used for client authentication.

Syntax

fdmsreversalcontrol.SSLCertSubject[=string]

Default Value

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:


Field	Meaning
CN	Common Name. This is commonly a hostname like www.server.com.
O	Organization
OU	Organizational Unit
L	Locality
S	State
C	Country
E	Email Address

If a field value contains a comma, it must be quoted.

Data Type

String

SSLProvider Property (FDMSReversal Control)

This specifies the SSL/TLS implementation to use.

Syntax

fdmsreversalcontrol.SSLProvider[=integer]

Possible Values

sslpAutomatic(0), 
sslpPlatform(1), 
sslpInternal(2)

Default Value

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the control will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:


0 (sslpAutomatic - default)	Automatically selects the appropriate implementation.
1 (sslpPlatform)	Uses the platform/system implementation.
2 (sslpInternal)	Uses the internal implementation.

Additional Notes

In most cases using the default value (Automatic) is recommended. The control will select a provider depending on the current platform.

When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.

Data Type

Integer

SSLServerCertEncoded Property (FDMSReversal Control)

This is the certificate (PEM/Base64 encoded).

Syntax

fdmsreversalcontrol.SSLServerCertEncoded

Default Value

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertEncodedB.

This property is read-only and not available at design time.

Data Type

Binary String

Timeout Property (FDMSReversal Control)

A timeout for the control.

Syntax

fdmsreversalcontrol.Timeout[=integer]

Default Value

Remarks

If Timeout is set to a positive value, and an operation cannot be completed immediately, the control will return with an error after Timeout seconds.

The default value for Timeout is 30 (seconds).

Data Type

Integer

TransactionId Property (FDMSReversal Control)

Transaction Id from the original response.

Syntax

fdmsreversalcontrol.TransactionId[=string]

Default Value

Remarks

This property should be set with the Response.TransactionId from the transaction you wish to reverse.

Data Type

String

TransactionNumber Property (FDMSReversal Control)

Uniquely identifies the transaction.

Syntax

fdmsreversalcontrol.TransactionNumber[=string]

Default Value

Remarks

The TransactionNumber (otherwise known as the Client Reference Number, or ClientRef) uniquely identifies the packet sent by the application to the Datawire system. This parameter stores some unique token of information, and is used to match the response to the initial request sent. For example, the client application could use a static counter that is increased with the each executed request.

For all controls except FDMSGiftCard the maximum length of this property is 14 alphanumeric characters.

The FDMS recommended format is "tttttttVnnnnrrr" where ttttttt is a 7 digit transaction id, V is a constant, and nnn is a 3 digit version number and rrr is a 3 digit revision number. The 6 digit version number is typically static but unique for an application (Example: Version 2.5 = tttttttV002500).

For the Rapid Connect platform, the 6 character version number should be your Project/TPPID value. The entire TransactionNumber must be unique within a 24 hour time period.

The FDMSGiftCard also passes this value to the FDMS Closed Loop Gift Card system as a transaction id, and therefore the following restrictions are enforced: The maximum length is 7 characters. If the first character is an 'X', the remaining characters must be in the range '0' through 'F', indicating a hexadecimal number. Otherwise the FDMS Closed Loop Gift Card system only allows digits in this property.

Data Type

String

URL Property (FDMSReversal Control)

Location of the Datawire server to which transactions are sent.

Syntax

fdmsreversalcontrol.URL[=string]

Default Value

"https://staging1.datawire.net/sd/"

Remarks

This is the URL to which all authorization and settlement transactions are sent. This URL is acquired by using the FDMSRegister control. Once you Register and Activate the merchant using the FDMSRegister control, you may then do a Service Discovery. After sending a Service Discovery transaction, the Datawire system will return a list of transaction URLs. The URL from this list with the shortest round-trip transit time from a ping is the URL you should use here.

Note: By default, this property is populated with the Datawire Staging (test) server, and is not the correct URL to use in a production environment. In a production environment, this URL is supplied by the FDMSRegister control.

Data Type

String

ValidationCode Property (FDMSReversal Control)

Validation Code from the original response.

Syntax

fdmsreversalcontrol.ValidationCode[=string]

Default Value

Remarks

This property should be set with the Response.ValidationCode from the transaction you wish to reverse.

Data Type

String

Config Method (FDMSReversal Control)

Sets or retrieves a configuration setting.

Syntax

fdmsreversalcontrol.Config ConfigurationString

Remarks

Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Interrupt Method (FDMSReversal Control)

Interrupts the current action.

Syntax

fdmsreversalcontrol.Interrupt

Remarks

This method interrupts any processing that the control is currently executing.

Reset Method (FDMSReversal Control)

Clears all properties to their default values.

Syntax

fdmsreversalcontrol.Reset

Remarks

This method clears all properties to their default values.

Reverse Method (FDMSReversal Control)

Reverses a credit card transaction.

Syntax

fdmsreversalcontrol.Reverse

Remarks

The following example starts with a simple $3 manually-keyed retail transaction:

  
  FDMSRetail1.TransactionNumber = 3;
  FDMSRetail1.TransactionAmount = "300";
  FDMSRetail1.Card.Number = "4111111111111111";
  FDMSRetail1.Card.ExpMonth = 12;
  FDMSRetail1.Card.ExpYear = 13;
  FDMSRetail1.Card.EntryDataSource = edsManuallyEntered;
  FDMSRetail1.Authorize();

 
  FDMSReversal1.MerchantNumber         = FDMSRetail1.MerchantNumber;
  FDMSReversal1.MerchantTerminalNumber = FDMSRetail1.MerchantTerminalNumber;
  FDMSReversal1.DatawireId             = FDMSRetail1.DatawireId;
  FDMSReversal1.URL                    = FDMSRetail1.URL;
  FDMSReversal1.Card.Number            = FDMSRetail1.Card.Number;
  FDMSReversal1.Card.ExpMonth          = FDMSRetail1.Card.ExpMonth;
  FDMSReversal1.Card.ExpYear           = FDMSRetail1.Card.ExpYear;
  FDMSReversal1.Card.EntryDataSource   = FDMSRetail1.Card.EntryDataSource;

  FDMSReversal1.ApprovalCode     = FDMSRetail1.Response.ApprovalCode;
  FDMSReversal1.TransactionId    = FDMSRetail1.Response.TransactionId;
  FDMSReversal1.AuthorizedAmount = FDMSRetail1.TransactionAmount;
  FDMSReversal1.ReturnedACI      = FDMSRetail1.Response.ReturnedACI;
  FDMSReversal1.ValidationCode   = FDMSRetail1.Response.ValidationCode;

  FDMSReversal1.TransactionNumber = 4;
  FDMSReversal1.SettlementAmount  = "100";
  FDMSReversal1.Reverse();

If the reversal is successful the ResponseApprovalCode will contain either "AP868686" or "AP888888", indicating the reversal was accepted.

Connected Event (FDMSReversal Control)

This event is fired immediately after a connection completes (or fails).

Syntax

Sub fdmsreversalcontrol_Connected(StatusCode As Integer, Description As String)

Remarks

If the connection is made normally, StatusCode is 0 and Description is "OK".

If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

DataPacketIn Event (FDMSReversal Control)

Fired when receiving a data packet from the transaction server.

Syntax

Sub fdmsreversalcontrol_DataPacketIn(DataPacket As String)

Remarks

This event fires when a packet is received. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or to extract additional response properties beyond the scope of this control.

DataPacketOut Event (FDMSReversal Control)

Fired when sending a data packet to the transaction server.

Syntax

Sub fdmsreversalcontrol_DataPacketOut(DataPacket As String)

Remarks

This event fires right before each data packet is sent. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or may be modified to support additional features beyond the scope of this control.

Disconnected Event (FDMSReversal Control)

This event is fired when a connection is closed.

Syntax

Sub fdmsreversalcontrol_Disconnected(StatusCode As Integer, Description As String)

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

Error Event (FDMSReversal Control)

Fired when information is available about errors during data delivery.

Syntax

Sub fdmsreversalcontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

SSLServerAuthentication Event (FDMSReversal Control)

Fired after the server presents its certificate to the client.

Syntax

Sub fdmsreversalcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (FDMSReversal Control)

Fired when secure connection progress messages are available.

Syntax

Sub fdmsreversalcontrol_SSLStatus(Message As String)

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

Status Event (FDMSReversal Control)

Shows the progress of the FDMS/Datawire connection.

Syntax

Sub fdmsreversalcontrol_Status(Message As String)

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

Config Settings (FDMSReversal Control)

The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

FDMSReversal Config Settings

AVSResult: Contains the Address Verification System result code of the transaction to be reversed.

This field should be set with the Response.AVSResult from the transaction you wish to reverse.

ClientTimeout: Indicates timeout client application will wait for response.

This setting indicates the interval of time, in seconds, a client will wait for the response for any given request. Normally this value is set to a value 5 seconds less than the Timeout value to allow for a response to be received from Datawire. It may be changed independently by setting this configuration setting AFTER setting the Timeout property. Note that too small a value will cause Datawire to reject a transaction immediately.

ECI: Electronic Commerce Indicator.

The Electronic Commerce Indicator is automatically set by the control dependent upon the DirectMarketingType and IndustryType. This configuration setting should be set to the value used within the Electronic Commerce transaction that you are reversing.

IsCOF: Set this to process a Credential On File transaction.

To process a Credential On File transaction you need to set this IsCOF flag to True. Default value is False.

IsOnlineRefund: Indicates whether you are reversing an Online Refund transaction.

Set this config to True when you are reversing an Online Refund transaction. Note: Currently only Amex does NOT support Online Refund.

PINCapability: The PIN Capability of the terminal.

This setting allows you to specify the PIN Capability of the terminal. The available values are:


Value	Description
0	Unknown
1	Terminal can accept PIN.
2 (default)	Terminal cannot accept PIN.
8	Pad is down.
9	PIN verified by terminal device.

RawRequest: Returns the request sent to the server for debugging purposes.

After an operation this setting may be queried to return the request as it was sent to the server. This is useful for debugging purposes.

RawResponse: Returns the response received from the server for debugging purposes.

After an operation this setting may be queried to return the response as it was received from the server. This is useful for debugging purposes.

TotalAuthorizedAmount: The total amount authorized including all incremental authorizations.

This field is used to specify the total amount authorized for the transaction you wish to reverse, including incremental authorizations. If reversing a single authorization, without additional incremental authorizations, you can simply set AuthorizedAmount and the component will set this field for you in the request. However when reversing a transaction with incremental authorizations, this field must be set to the total amount authorized (first authorization plus all additional incremental authorizations). The AuthorizedAmount property should be set to the first authorized amount (from the initial authorization transaction).

TCPClient Config Settings

ConnectionTimeout: Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the control will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect: Tells the control whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by controls that do not directly expose Firewall properties.

FirewallHost: Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by controls that do not directly expose Firewall properties.

FirewallPassword: Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the control fails with an error.

Note: This setting is provided for use by controls that do not directly expose Firewall properties.

FirewallPort: The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by controls that do not directly expose Firewall properties.

FirewallType: Determines the type of firewall to connect through.

The appropriate values are as follows:


0	No firewall (default setting).
1	Connect through a tunneling proxy. FirewallPort is set to 80.
2	Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3	Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10	Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by controls that do not directly expose Firewall properties.

FirewallUser: A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the control fails with an error.

Note: This setting is provided for use by controls that do not directly expose Firewall properties.

KeepAliveInterval: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime: The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger: When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the control returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime: Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost: The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.

If the control is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

LocalPort: The port in the local host where the control binds.

This must be set before a connection is attempted. It instructs the control to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength: The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate: The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList: A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive: Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay: Whether or not to delay when sending packets.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

UseIPv6: Whether to use IPv6.

When set to 0 (default), the control will use IPv4 exclusively. When set to 1, the control will use IPv6 exclusively. To instruct the control to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:


0	IPv4 Only
1	IPv6 Only
2	IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets: Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if SSLProvider is set to Platform.

OpenSSLCADir: The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile: Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList: A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData: The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

ReuseSSLSession: Determines if the SSL session is reused.

If set to true, the control will reuse the context if and only if the following criteria are met:

The target host name is the same.
The system cache entry has not expired (default timeout is 10 hours).
The application process that calls the function is the same.
The logon session is the same.
The instance of the control is the same.

SSLCACerts: A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL: Whether to check the Certificate Revocation List for the server certificate.

This setting specifies whether the control will check the Certificate Revocation List specified by the server certificate. If set to 1 or 2, the control will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The control will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the control fails with an error.

When set to 0 (default) the CRL check will not be performed by the control. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCheckOCSP: Whether to use OCSP to check the status of the server certificate.

This setting specifies whether the control will use OCSP to check the validity of the server certificate. If set to 1 or 2, the control will first obtain the OCSP URL from the server certificate's OCSP extension. The control will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the control fails with an error.

When set to 0 (default) the control will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCipherStrength: The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLEnabledCipherSuites: The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the control will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include:

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:

TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols: Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:


TLS1.3	12288 (Hex 3000)
TLS1.2	3072 (Hex C00) (Default)
TLS1.1	768 (Hex 300) (Default)
TLS1	192 (Hex C0) (Default)
SSL3	48 (Hex 30) [Platform Only]
SSL2	12 (Hex 0C) [Platform Only]

SSLEnabledProtocols - TLS 1.3 Notes

By default when TLS 1.3 is enabled the control will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.

In editions which are designed to run on Windows SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is only supported on Windows 11 / Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider) please be aware of the following notes:

The platform provider is only available on Windows 11 / Windows Server 2022 and up.
SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

SSLEnabledProtocols: SSL2 and SSL3 Notes:

SSL 2.0 and 3.0 are not supported by the control when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.

SSLEnableRenegotiation: Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is by default, but can be set to to disable the extension.

This setting is only applicable when SSLProvider is set to Internal.

SSLIncludeCertChain: Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

SSLKeyLogFile: The location of a file where per-session secrets are written for debugging purposes.

This setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the control will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the control will only append, it will not overwrite previous values.

Note: This setting is only applicable when SSLProvider is set to Internal.

SSLNegotiatedCipher: Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength: Returns the negotiated cipher suite strength.

Returns the strength of the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g.TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite: Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange: Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength: Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedVersion: Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags: Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:


0x00000001	Ignore time validity status of certificate.
0x00000002	Ignore time validity status of CTL.
0x00000004	Ignore non-nested certificate times.
0x00000010	Allow unknown Certificate Authority.
0x00000020	Ignore wrong certificate usage.
0x00000100	Ignore unknown certificate revocation status.
0x00000200	Ignore unknown CTL signer revocation status.
0x00000400	Ignore unknown Certificate Authority revocation status.
0x00000800	Ignore unknown Root revocation status.
0x00008000	Allow test Root certificate.
0x00004000	Trust test Root certificate.
0x80000000	Ignore non-matching CN (certificate CN not-matching server name).

This functionality is currently not available when the provider is OpenSSL.

SSLServerCACerts: A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----END CERTIFICATE-----

TLS12SignatureAlgorithms: Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the control will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the control fails with an error.

The format of this value is a comma separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups: The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1" (default)

TLS13KeyShareGroups: The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

"ecdhe_x25519" (default)
"ecdhe_x448"
"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1"
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096"
"ffdhe_6144"
"ffdhe_8192"

TLS13SignatureAlgorithms: The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

"ed25519" (default)
"ed448" (default)
"ecdsa_secp256r1_sha256" (default)
"ecdsa_secp384r1_sha384" (default)
"ecdsa_secp521r1_sha512" (default)
"rsa_pkcs1_sha256" (default)
"rsa_pkcs1_sha384" (default)
"rsa_pkcs1_sha512" (default)
"rsa_pss_sha256" (default)
"rsa_pss_sha384" (default)
"rsa_pss_sha512" (default)

The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This setting is only applicable when SSLEnabledProtocols includes TLS 1.3.

TLS13SupportedGroups: The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

"ecdhe_x25519" (default)
"ecdhe_x448" (default)
"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1" (default)
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096" (default)
"ffdhe_6144" (default)
"ffdhe_8192" (default)

Socket Config Settings

AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

FirewallData: Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

InBufferSize: The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize: The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
