Re: Load balancers and large deployments?

[Steve Hillman <hillman@sfu.ca>]

We're doing load balancers as well (F5's), but only for the login page. Once you login, you get directed to "your" mailbox server, which still goes through the load balancer to act as a firewall, but not to do balancing.  SOAP requests for a given user must always be sent to that user's mailbox server, unless you have the HTTP proxy set up, which is introduced in 5.0.5 but is still beta as of 5.0.6

We only have a few hundred users on our system so far (ramping up next month), but we haven't had any reported Zimlet problems.
