Re: new connection for every call! Keep-alive?

Sat, 27 May 2006 09:29:36 -0700 

Hi again,

OK, I hope that I have got this wrong!
When using HTTPConstants.REUSE_HTTP_CLIENT, it seems that the connection is not released (added to connectionPool.freeConnections) and that means that a new connection is inserted into the connectionPool for each SOAP call. So if you make more calls than hostPool.numConnections (which is apparently 2 by default), then the thread will hang and wait for a connection to be released and that will not happen!
Has anybody got a clue of what I am doing wrong here? Please, help. How can I reuse a http connection? 


This is what I am using for the test.

Hi Davanum Srinivas,
Thank you for the answer. In fact I did already dig that information out from the source code, and have tried it, but reusing the HttpClient does not mean that the *connection* is reused. Try to use ethereal and see. The port number changes for every call. I understood that the http property "Keep-alive" means that the actual socket connection is reused for every http request/response between the same client/server pair.

Hello happy axis users,
How do I prevent axis2 client from making a new connection for every call? 

I have built a client app based on the axis2 v1.0. The client is built
like the EchoBlockingClient userguide sample. It seems that every call
is done by a opening a new connection to the server. There doesn't seem
to be any Keep-alive property in the http header. I have searched in the documentation and in the source code for a hook to switch Keep-alive on, 
but did not succeed. So I just added a setRequestHeader into the
SOAPOverHttpSender.java. Now I get the Keep-alive in the http header,
but it still seems that a new connection is opened for each call.

Please, help me with a hint on how to reuse connections.
