Load balanced web servers?

Does anyone have experience with putting the RT web interface on a pair
of load-balanced web servers? I’d imagine it would work fairly smoothly,
since most information is stored in the database, but figured I’d check
here first for any horror stories.

What we’ve got is a set of external services that will be load-balanced
(more for redundancy that actual load issues), and I’d like to throw
our RT3 install on there as well.

thanks,
