The return code indicating that a connection to the proxy server
was dropped. If the connection is via HTTP tunneling
this return code indicates the client tried
to use a session that was previously cleaned up by the system.
The system cleaned up the session because it was idle long
enough to indicate the client is no longer active. If
the client was still active
increase the timeout property so the system
waits longer before cleaning up sessions.
The return code indicating that communication failed to the proxy
server because of a mismatch between code levels. This usually
occurs if the client and proxy server are running with different
versions of the IBM Toolbox for Java or different versions
of the JVM.
