In ref to using perl, You can't connect to the database for each thread?

It appears that the perl DBI isn't thread safe, so that rules out
Perl.

Anytime I decide to include AGI into an application, I try to keep most of
the code and logic inside the AGI. I have successfully written FastAGI
applications in python, and it was a good experience.
What state are you speaking of? I don't quite follow.


Did you have multiple AGI scripts, broken down by function, or did you
