Embperl uses Apache::Session to store session information (%udat). If
you have successfully configured session handling you shoul see in
error log smth. like this: SES: Embperl sessions enabled (>=1.xx) where
in brackets the version of Apache::Session you use.

Check out the man on Apache::Session::MySQL and you will soon find it
out. If yor servers are load balanced i think this really doesn`t
matter because if a client has a cookie with it`s session id, so it
can be retrieved from the backend sql server you use to store the
data. Correct me if it is not right (never used load balancing).
