Apache::AuthCookie or Apache::AuthDBI or Apache::???

[Kenneth Frankel]

What's the best way to authenticate users?  I have a site where the entire 
site is to be protected. I want to log users in at the front of the web 
site, and keep them logged in as they travel around.   I was trying to get 
AuthCookie to work but haven't been successful so far.  Should I continue 
down this route?  Is Apache::Session + AuthBasic better?  Or is AuthDBI?  I 
have a mysql database handy.  What's the most popular Auth method 
nowadays?  Is there a popularity/usage chart compiled anywhere?

Thanks in advance!
