ApacheRevProxy doing URL rewrite to https://external.domB.com
ApacheRevProxy fetching URL via SquidCache


Under Bug: 19188 there was a patch posted to get around this issue.
http://issues.apache.org/bugzilla/attachment.cgi?id=11552

This patch works well; under 2.0.48, but is not applicable to the current 2.2
stream.

Is it possible to get the patch changed to apply to 2.2 or current issue address
please? 

Below are the current configs and debug from output.
Apache sends back to the client:
     Service Temporarily Unavailable
