The manual page I referenced *seems* to say either that squid acts as the 
SSL endpoint or that squid uses something it calls a CONNECT tunnel to 
pass the session through to the browser without itself acting as an end-
point. Apparently RFC 2817 gives the gory details of CONNECT tunnels, so 
maybe you should look at this since you appear to know more than I do 
about SSL internals.
