It's easy to use the "RequestHeader append Proxy-Authorization" to create a forward proxy with no authentication that bounce over a password protected one. But this header is not append to CONNECT requests... I'm aware of the patch suggested at https://issues.apache.org/bugzilla/show_bug.cgi?id=37355, but it does not seems to be integrated in the trunk/release branch
Is there another way to configure the remote proxy authorization credentials (and could be used in CONNECT transactions) ?
