Blocker Description
When doing a forward proxy setup, and a request like this is processed:
GET https://127.0.0.1 HTTP/1.0
Host: 127.0.0.1
where 127.0.0.1:443 is not listened on, then two things will happen:
1) The client connection "hangs".
2) When client disconnects, we segfault (see trace below).
It is understood that ATS does not support forwarding proxy of HTTPS like this, instead we support CONNECT which is what (most) clients will use to forward proxy HTTPS. But, obviously it's not acceptable to segfault under these conditions. Note that this problem is only there if the server is setup to handle forward proxy, i.e. remap.required is set to '0'.
