Does SSL require a different IP address in every case?

Does SSL require a different IP address in every case?

For example, if I have a SSL wildcard and one Apache server with one IP address, can I use SSL for each of the domain aliases? If so, how?

You don't need separate IP addresses - you can use Server Name Indication (SNI) with VirtualHosts:

[wiki.apache.org...]

The only caveat is if you need to support IE on Windows XP or earlier, which can't handle SNI - but that's not normally an issue these days.

Yes, found reference to SNI but yet to get that working.

As far as browsers go, not every browser yet supports SNI, but the most popular browsers do, and some have for quite a while. This includes Firefox 2.0 or later, Opera 8.0 or later, Internet Explorer 7.0 or later (unfortunately, only on Vista), Google Chrome, and Safari 3.2.1 (unfortunately only on OS X 10.5.6 or later).

So SNI won't be much use because a lot of computers are still running XP.

Sill investigating.

I now have SNI working with a SSL wildcard and multiple sites.

It works OK on Windows XP using IE8. IE7 may not work but all XP users should have updated to IE8.
