[PATCH] proxy_util.c: ap_proxy_determine_connection connecting improper HTTPS backend

[Hendrik Harms]

If an (improper) backend server could only serve requests with "abs_path"s
but not "absoluteURI"s (RFC 2616 5.1.2) we couldn't place this backend
behind a forward proxy using https.

https://issues.apache.org/bugzilla/show_bug.cgi?id=55892

This patch would solve this. I've added the "force-proxy-request-1.0"
switch into this patch but I'm not sure about this.
