Extending the HTTP persistent timeout on the WebSphere proxy server

You can extend the HTTP persistent timeout on the IBM® WebSphere® proxy server to stay connected longer.

Before you begin

About this task

The default rtc4web timeout value is 30 seconds. This is the default timeout for the WebSphere proxy server persistent timeout setting, too. This can causes a rare condition to occur where both sides of the connection can let go at the same time. In order to minimize this conflict, extend the WebSphere proxy server HTTP Persistent timeout to stay connected longer.
