eToys used mod_session to give users cookies because many of the pages 
on the site were served from the cache on the proxy server and never 
touched the mod_perl server.  If we waited for them to hit a page that 
went to the mod_perl server, we wouldn't have been able to track their 
movements on the site before that.  We had the proxy configured to log 
the session ID on every hit, so we could produce a click trail through 
the site for each person.

If you have a similar issue that you need to deal with, you should be 
able to make Catalyst's session plugin use a cookie generated by 
mod_session or something similar.  (I use mod_auth_tkt most of the time 
these days.)  For most sites, it's probably not important to issue a 
cookie on static pages.  Many people get their click trail analysis from 
something like Google Analytics these days.
