Hello,

We currently have a cluster of PHP web servers setup for serving our PHP applications. These servers are configured to use memcached to store PHP session info. This works great for Moodle, it gives us good performance and all servers in the cluster have access to a common PHP session store.

For whatever reason, this configuration does not work for Mahara. It would appear that sessions are being handled in a different way such that switching the underlying data store breaks the software. We can get Mahara to work in a clustered enviornment using an NFS file share for storing the sessions but the performance is horrible.

Is there any possibility of making some changes to the code that would make the software support memcached for storing PHP sessions? I would be happy to look at it, but it would be helpful if someone could point me to the areas that would need to be reworked.

Thanks!
