[sf-perl] Catalyst question - sharing data between sessions

So I'm not clear about a few things. You say that you want to share
some context between sessions. Is this between two different user
sessions, or reload the same session for one user with all its data
more than once? You also say that you clear the stash after every
request. Does this mean you want to clear all the data? This
wouldn't make sense for reloading the same session for a single user,
and if its multiple users they would only be able to share data if the
requests were happening simultaneously.
I *think* what you're asking for is the concept of persistent session
data that is available for a single user on every request they make.
This is pretty easy to setup on Catalyst:
If you want to share data between processes and don't want to incur
hits to your DB, maybe you want Memcached.
