[mapguide-users] Load balancing and RFC3

I've seen that in RFC3
<http://trac.osgeo.org/mapguide/wiki/MapGuideRfc3> was proposed (and
implemented in 1.2) to use a load balancing scheme that allows to have
multiple site server under one web tier.
In order to cope with sessions, each user should be served by the same
server that fulfills his/her first request and at each new client the
server is chosen in a round-robin fashion.

Does everyone have tried this?
I want to try this solution since the performances with 1 server are
quite poor (several seconds to zoom or pan in map with a few Postgis
layers), and moreover, CPU usage  goes near to 100% for 3-4 seconds at
each request. I think that with one server service time would be quite
long if there are several request together.

I've tried with version 1.2 and it doesn't work properly. Requests
from different clients are correctly dispatched to my two servers but
the server that is not in the same machine of the web tier keeps
telling that the session is expired or non valid.

I've configured webconfig.ini as in RFC3.
Am I missing something?

Gabriele
