Hi,

We have been running into some performance problems with using the HTTPRequest node on WMB 6.1. The problem was that the TCP/IP connection between WMB and WAS - where our web service is hosted - was being closed and opened. This was even after setting the following;

1. HTTP 1.1 on HTTPRequest node along with setting the KeepAlive check box
2. Set maxKeepAliveRequests to 0 on the broker
3. Set tcpNoDelay to true on the broker

We finally tracked down to the situation where when the web service returns a SOAP Fault the HTTPResponse header contains Connection: close which is then forcing the HTTPRequest node to close the connection and re-open a new one. Which I guess is the standard behavior and follows the HTTP 1.1 specs.

But what I am struggling is with is how I can ensure that the Connection: close is not sent back from the web services. It looks like a basic behavior of the WebSphere Application Server and Servlet response.

Any ideas?

Thanks
