TCP Options (tcpOptions)

Defines TCP protocol settings.

Attribute name Data type Default value Description
id string   A unique configuration ID.
inactivityTimeout A period of time with millisecond precision 60s Amount of time to wait for a read or write request to complete on a socket. This value is overridden by protocol-specific timeouts. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), seconds (s), or milliseconds (ms). For example, specify 500 milliseconds as 500ms. You can include multiple values in a single entry. For example, 1s500ms is equivalent to 1.5 seconds.
soReuseAddr boolean true Enables immediate rebind to a port with no active listener.
addressExcludeList string   A list of addresses that are not allowed to make inbound connections on this channel. IPv4 or IPv6 addresses can be specified. All values in an IPv4 or PIv6 address must be represented by a number, or an asterisk that is used as a wildcard character.
addressIncludeList string   A list of addresses that are allowed to make inbound connections on this channel. IPv4 or IPv6 addresses can be specified. All values in an IPv4 or PIv6 address must be represented by a number, or an asterisk that is used as a wildcard character.
hostNameExcludeList string   A list of host names that are not allowed to make inbound connections on this channel. Host names can start with an asterisk, which is used as a wildcard character. However, an asterisk must not appear elsewhere in the address. For example, *.abc.com is valid, but *.abc.* is invalid.
hostNameIncludeList string   A list of host names that are allowed to make inbound connections on this channel. Host names can start with an asterisk, which is used as a wildcard character. However, an asterisk must not appear elsewhere in the address. For example, *.abc.com is valid, but *.abc.* is invalid.
maxOpenConnections integer 128000 The maximum number of open connections per HTTP Endpoint. The range of possible values is between 1 and 1280000. This value is not strictly enforced to the exact value that is configured due to the timing of connections opening and closing.
