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
