You can't cache passed-through SSL traffic.  In your situation, I
usually setup the apache server to be unencrypted, but then run Pound
(http://www.apsis.ch/pound) to receive the SSL traffic, decode it,
and then pass it  to the apache server.  Of course, I usually run
these on different servers, allowing multiple back-end servers to
hide behind a single Pound front end.

I wouldn't think you'd see much gain by running squid on the same
machine as apache.
