Re: [jetty-users] Jetty client v8.0.4 - problem opening HTTPS connection through HTTP proxy server
|
Hi Gilman,
Could you attach the actual tcp dump file? If you cannot, then please open an
issue and attach it. The issue tracker is at:
https://bugs.eclipse.org/bugs/buglist.cgi?cmdtype=runnamed&namedcmd=jetty-bugs
Also, have you turned on debug , and overridden the onException(),
onConnectionFail(), onExpire() methods of ContentExchange?
thanks
Jan
