advice on Apache::DBI Apache::Session and Apache::AuthCookieDBI intergration

[Clayton Cottingham aka drfrog]

Hi all,
ive just been researching these
a bit and I'm wondering if anyone has good advice/links on how to 
link these three Modules together ?


heres what im caught on :
1.is it best to load Apache::DBI at start up of apache and can i load more than
one connection type?
2.is it best to login and then set session or set session and then log in
3. what about 'last session' type storage
4. if Apache::DBI is on at startup how can i load a specific connection type
for Sessions?

i think that's all  the really big questions i have
