I should point out that I don't use apache-ssl but apache using mod_ssl.
I can't tell you the differences (since I've never used apache-ssl - but they are two completely different products (with mod_ssl starting off as a branch of apache-ssl I think)), and the only reason I use mod_ssl instead is because it came bundled with Slackware 9.1. I don't know which is better, nor do I particularly care at the moment
Anyhoo - check it out here:
http://www.modssl.org/
(oh, and the documentation that comes when you install mod_ssl is superb . It can be found at
http://localhost/manual/mod/mod_ssl/ once you install it).
