Ernie --
I am playing through this idea as you can see from the other load balancing
thread. But just my thoughts on your issue ..
If the director can use some sort of sticky sessions (ah .. thats the word I
was looking for !) then it can direct requests from one user to the *same*
webserver. Thereafter you can have one webserver <--> one servlet engine
combination which will not need any session info sharing amongst the JVM per
se. Anything common can be in the DB may be ?!
I am not sure about the other architecture where we can have one webserver
and multiple servlet engines with a built-in director (?) to stick the
session to the corresponding servlet engine. Is that what Apache - JServ
combination does ? Can it be extended to any webserver ? I dunno ..
