Sushil :
In case you are having all the servers load balanced on a single local
director , the local director will make sure that when the request is
directed from a single browser session it will always be directed to the
same web server/appserver .
The persistant session option is for the case when a user is hitting one
particular server and suddenly the machine goes down , in this case the
session details are stored in the database and when the request is directed
to a different appserver the session details are read from the database .
Thanks

Subject: Multiple AppServer: Session Problem
Hi:
We have developed an e-commerce site using "MVC Model 2" architecture.
Classes/JavaBeans - Model
Servlet - Controller
JSP - View
We are running Six WebSphere 3.02 AppServer on six difference unix box
(AIX) . We are facing a severe architecture problem. Here all AppServer
are having difference session i.e. there is no relation between all
these AppServers That means, if a customer is talking to AppServer1 and
on the next request if customer redirects to AppServer2 (Due to
LoadBalancer), then it will be a new SESSION i..e all the SESSION data
is lost.
Now I am unable to decide how we can solve this problem without
modifying the code.
I was looking for documentation, here is the list of solutions:
- IP Affinity
- Session Affinity
- Persistance Session
Any suggestion/ideas will be highly appreciated.
Thanks.
Sushil Singh
