Hi Deepak, continuing with our conversation, for your configuration you've
to setup a http farm which has already applied the Xforwarder-for header
and for equal sharing you've to configure the same weight for every
backend. This kind of farm provides much more performance than the TCP one
for HTTP transactions.
Regards.
