Re: Clustering question...

As I was not involved in the design decision, I can not say whether or 
not that it is a good call or not. But the reason that we need 
application context replication is that the entire site serves up  
relatively static data(infrequent updates) to all of it the users. They 
did not feel that hitting the DB every time a page is accessed was 
efficient.

ie, what ever got stored in application context on server A, should have got
stored on B by the same mechanism, not by session replication.
Is there a huge need to replicate context data?

Subject: Clustering question...
 

Hi All,
 I have question about synchronizing data within the application
context. If the data of a webapp's application context changes within
one of the nodes in the cluster, how does the other nodes get the
updated application context data? Is it handle the same way as user
session data(via some session manager implementation)? Or does the
change(s) get distributed?
Thanks for any help you can give,
Rick Szeto
