Woah, I guess my question was ambiguous. I'm not talking about data persisting from one page access to the next for a given user. I'm talking about data persisting from one user to the next for a given web server process. I'm talking about data that will be inserted into the template for every single page access, so I don't want to add an extra database call. And data that changes very infrequently, actually probably never once the site goes live. The solution we always used with mod_perl was just to declare a static hash and do lazy memoizing of any values looked up in the database by stuffing them in the hash. The next page access for the next user would check the hash first before checking the database. When the values in the database changed the values on the web site wouldn't update until the processes exited and new processes were forked, which would take 10-15 minutes. -- greg
