PSQuad33 asked some questions on the #jetty IRC.... but left before I could answer.
so come in PSQuad33? post the questions here or I'll see you in #jetty.
But the short answer is that if you are trying to do a non transparent proxy,
ie configure the browsers with your proxy ip and port... then you cannot use
an SSL listener. SSL requests are proxied using the CONNECT method which makes
an end to end tunnel with the destination server. No SSL is done by the proxy.
