[squid-users] SQUID Reverse Proxy not forwarding requests to Apache web server

My squid server 3.1.6 sits in dmz. On this server, I am running
apache server 2.2.9. My goal is to a) cash owa responses b) forward
https owa requests to the Apache server on port 8443 c) The Apache
server forwards the request to internal exchange server.

Below, is my squid reverse proxy configuration. The domain
webmail.mydomain.com resolves to the of external interface of the
exchange server. However, I am saying, in configuration, that
cache_peer is localhost. Nevertheless, the https request is never
forwarded to apache server. Rather, it is going directly to the
external interface of the exchange server.

Where am I going wrong here?
