Note: this article was originally written for Chamilo 1.9 but it is also valid for all versions 1.10 and 1.11. We seldom receive a request from users of Chamilo LMS saying their sessions are cut in the middle of their activity. And sure, it might so happen that you are in the middle of the redaction of a very large answer to an open question, or diserting on how the course is going to help you in the forum. And we get that it's super-frustrating to click "submit" and then get an error page.

In Drupal's Boost module, there is a feature setting a cookie called DRUPAL_UID that then lets Apache (or whatever web server you have) avoid serving cached pages to authenticated users. Well it seems this feature was broken sometime in 2011-2012 (before July 2012), so you might have banged your head against the wall trying to understand why your login box still appeared after login, or some similar effect. Well, bang it no longer.
