Using session id for load balancing

["David M. Rosner" <da...@recommend-it.com>]

Hi All,

We use a Foundry Server Iron switch to load balance our Tomcat application 
servers. I recently discovered that it uses IP addresses to determine which 
server to send the user back to. Problem is many networks may use different 
IP addresses for a single client for different requests.

The way around this is to configure my Server Iron to use the cookie that 
Tomcat sets (jspsession) to determine which server to send the user to. But 
if the user has shut off cookies then Tomcat will revert to URL rewriting. 
My question is, how can I setup Tomcat so that even if it is using URL 
rewriting on a session it will attempt to write the cookie anyway? Also, 
I'd be interested in hearing other solutions from anyone else who is using 
a load balancer.

Thanks!
