Hi,
I have just been given some more information. The architecture would
involve a DNS server perodically giving out a DNS address for one DNS
server and then an address for the other. Each data centre would have
multiple hosts, each running multiple tomcats. The load balancer would
take the incoming request and send it to one of the tomcat instances,
using a cookie to send the request back to the same tomcat instance.
I see there is clustering available with Tomcat, but I don't see how
this works across data centers, if at all.

Hi,
I have been asked to look into a solution that would involve a few
different data centres each with their own set of load balanced
Tomcat servers. The requirement is for the users not to lose their
session if one data center goes down. I have never had to work on
something this large and have no idea to what extent this can be
achieved with Tomcat.
My initial thoughts would be for each data center to have a session
pool, which is synced with each other, so if ever a Tomcat server or
data center goes down they can check in the pool to see if it exists
and then reuse that. It would mean extra communication behind the
scene, but I see no other way go about it.
Any help would be appreciated.
