  Then you configured the server to only send Session-Timeout on the first packet.

  The server does NOT send Session-Timeout by default.  So if it does... you edited it.  If the server sends Session-Timeout at the wrong time... you told it to send Session-Timeout at the wrong time.

  Go back and read the debug output.  Look at it across multiple sessions.  If you can't do this in production, build a test system.  It won't cost anything.

  Then, configure the server to send Session-Timeout correctly.

  I'll note that in all of this, you don't describe what you want to do.  You ask how to fix a particular problem.  This is usually the wrong approach.  If you describe what you want and what you have, we can probably suggest a solution that will work.

  If you keep asking questions which may very well be irrelevant, we won't be able to help you.  And we don't know if the questions are relevant (or not), because you're not describing what you want and what you have.
