Problem with caching - EP 6.0 with BSP iView

Hi,

I have build a BSP iView ( For a plan of BW-BPS ).When I execute this link ona fresh IE Browser I am able to successfully log in.But from the iview while running from the portal, when I log in to the BW system, it just throws me out and comes back to the same login screen.If I give a incorrect login if gives me the message.( No SSO had been configured now ).

I do face the same problem if I use the web link directly in old IE browser session, but not if I use a fresh session.

I assume this must be something to do with Caching.Any hints will be appreciated.

Regards,

Muinul
