[Bug 57795] mod_proxy_wstunnel sometimes does not connect and sometimes does not disconnect

--- Comment #10 from Ryan <Ry...@gmail.com> ---
It does appear that mod_proxy_wstunnel does not handle half-open connections
well.   If you setup Tomcat for websockets and then have a client pull their
network cable Tomcat will get a "connection forcibly closed by the remote host"
error on the session.   Do the same test going through mod_proxy_wstunnel to
get to Tomcat and the server isn't notified of the connection loss.  Worse, the
Session.isOpen() method returns true and sendMessage doesn't throw any
exceptions!   I don't know if this is due to TCP/IP keepalive or what.  Maybe
the proxy server responds that the connection is still alive, but fails to
check with the client.
