persistent-con-timeout
Syntax
persistent-con-timeout = number_of_secondsDescription
Indicates the maximum number of seconds a persistent connection can remain idle in a cache before the connection is cleaned up and closed by WebSEAL.
Use an integer value lower than the configured maximum connection lifetime for the junctioned web server. For example, the connection lifetime for a junctioned Apache web server is controlled by the KeepAliveTimeout configuration entry.
You can customize the persistent-con-timeout configuration
item for a particular junction by adding the adjusted configuration
item to a [junction:{junction_id}] stanza.
where {junction_id} refers
to the junction point for a standard junction (including the leading / character)
or the virtual host label for a virtual host junction.
If the [junction] max-cached-persistent-connections configuration entry is set to a value greater than zero, WebSEAL reuses its TCP/IP session with the junctioned back-end server. If the junctioned back-end server closes the socket at the same time that WebSEAL starts to use this session to send a request, the request fails.
To send the
request again, WebSEAL opens a new TCP/IP session. If the request
body is larger than the size that WebSEAL can cache, WebSEAL fails
to resend the request and generates a 500 error.
Options
