I'm trying to record some session based data into a database. I want to use the sessionID , but am not sure how unique it is. The data being recorded belongs to 2 application, each executes in its own JVM, possibly a different physical server .
So, is the HTTPSession ID universally unique?

Thanks!

Different JVMs may have generate different Session IDs.

But I would not bet the farm on it. Rather than relying on the ession ID, you'd be better off assigning a known unique value to each session to use as a database key, perhaps generated from a DB seuqence.

yes, I was going in that direction (using a DB generated key), and wanted to make sure it was the right approach.

Thanks for the replies!
