Hi Andrew,
I'm not able to access the load balanced Moodle 2.x right now; there are different admin groups for Moodle and Mahara. Right now I'm just guessing and collecting breadcrumbs...
As Moodle and the load balancer are in the same subsystem, I would think there is no ssl connection betwen them, but I might still be wrong.
I assume now that I will be able to connect Mahara to the load balanced system and that I won't have to care about which machine handles the request.
Thanks a lot for your help,
Uwe
