prevent session handling

[panagiotiss]

Hi is it possible in Joomla 3 to disable writing the guest sessions to the database?

thanks in advance

Without core-hacks, I am afraid this is not possible.

Look into using another session handler, such as APC or memcache(d) to reduce the load on the database.

Not only is it not possible, it's not advisable - also, what do you mean by "guest sessions"? AFAIK, only users that are registered and log into your site create an entry in the sessions table. And that is the preferred way to do it - in the database.
As for Jootify's advice, I propose you steer clear of memcache - it's good in itself, but its implementation in Joomla! is a little less fortunate. Try APC instead.

Joomla still uses the database for certain session handling stuff, even if you enable memcache/apc for sessions.

This is hardcoded into core, and there is a "TODO" entry in cms.php on line 741:

Code: Select all

// TODO: At some point we need to get away from having session data always in the db.

Also, Joomla does create sessions for guest users (aka users who are not logged in).
