Using WSRP in a clustered consumer and producer environment.

Question

We're currently in the design phase of a remote portlet project where our clustered portal will consume portlets from a different clustered portal. I've read the "Inside WSRP" found on dev2dev:
http://dev2dev.bea.com/pub/a/2005/03/inside_wsrp.html?page=4
Will the portal producer cluster need to be front-ended by something which load-balances the SOAP traffic across the managed servers in the portal producer cluster? We've been doing some testing with the iisproxy and it doesn't seem to work properly. Does this mean that we will need to front-end the portal producer cluster with another mechanism to LB?
Thanks!

Answer 1

Can you also check if the http cookies returned via initCookieResponse
are included in all the subsequent requests to the producer.

Please note that the same portlet works fine when deployed in a single server domain without Clustering.
