Subject HTTP client problem.
Date Mon, 14 Aug 2006 04:30:51 GMT
> Hello,
> 
> In our project we are using a http client server for SOAP
> communication. The http client is based on Axis. 
> 
> The http server responds to the client with the proper content-length
> indication. However, the http client is not closing the connection and
> keeping it alive. It looks like the Axis client is not able to read
> this and is timing out waiting for more messages. We get this error
> logged:
