I've used the PHP MVC framework Symfony to build an on-demand web app.
It has an annoying bug - the session expires after about 15-30 minutes of inactivity. There is a config directive to prevent session expiration but it does not work. Even workarounds such as this one did not help me.
I intend not to migrate to Symfony 1.1 (which fixes this bug) in the foreseeable future.
Has anyone been there and solved it? I would be most grateful for a hint or two!
