Re: OT (slightly): SSL Requirement

Yes and no

Ok - here is the quick break down - Authentication and verification
happen at the same time - For the most part the web is IP based - Thus
if I am looking for Jack @ 129.81.56.31 and Jilly @ 129.81.56.31 your
going to confuse the hell out of the web server that has a cert for
Bob.

Solution 1: L3 routers with Nat that can address a request for
Jill.mydomain.com and point to the correct internal IP even when Jill,
Jack, and Bob are all pointing to the same external IP

Solution 2: Use different port numbers

Solution 3: Use SNI (Server Name Indications) to have Apache check the
name then pass to the VHost for authentication and verification.

I personally recommend solution 3 but be aware the user will require a
"modern" browser and, in the case of a Mac, a newer OS for this to
work.
