Just be aware that it is not unusual for an IMAP client to open 2 (or
more) connections to a mail folder in the same session. It's pretty
common for a client to promptly open one connection to the INBOX so
to watch for new messages and have another that 'roams' around to
other mailboxes for fetching/storing messages. That 'roamer' may
return to the INBOX on occasion. With your load-balancer, you're
likely to have these various sessions end up on different IMAP servers
and thus see that cache-consistency problem that Mark keeps bringing
up. (unless that's a darned smart load-balancer which looks for
pre-existing sessions and tries to keep them together).
This is a non issue since the load balancer can be (and is) configured
to handle this correctly. If I'm mistaken, then in 3 years since I've
been here this has never happened and there are 40K users and they call
about everything else :-)
