Subject [HttpClient] wierd sudden connection close
Date Mon, 13 Sep 2004 08:23:26 GMT
Hello,

 

I'm using Httpclient to connect a java program to a servlet, sending back
and forth XML over http using POST method. I've written a sub program to
test my servlet. The sub program sends series of requests to the servlet.
Requests are not the same from a serie to another.

Generally, the sub program doesn't run until the end of the second serie,
there is a sudden connection close that ends up in a
java.net.SocketTimeoutException: Read timed out being raised.

 

A previous version of the subprogram was running perfectly OK, it used Http
GET method and URLEncoded params.

 

I'm about to try using a packet tracing program to see if a can get some
information.
In the meantime, if somebody could give me a clue about this, here is the
wire and context log for the last request:

 

Thanks in advance.
