Update:
I was able to solve for this by using Apache ProxyRemote Option. Here
is the working test configuration of Apache.
<VirtualHost *:80>
SSLProxyEngine On
SSLProxyCheckPeerCN on
SSLProxyCheckPeerExpire on
RewriteRule / https://remote.domain [P]
ProxyRemote "*" https://proxyIp:proxyPort
ProxyPass / https://remote.domain
</VirtualHost>
The POC configuration which worked for me is
Client => Haproxy => Apache => Squid => ELB
Unlike what many blogs listed, ProxyRemote worked without ProxyRequests on.
I tried researching lua with haproxy, but I couldn't figure out if I
can force a CONNECT via lua to the backend before haproxy starts
forwarding the request to backend.
