Portal Session content in BSP

Hello,

My BSP inside an iView is located in the xRPM content. What I now try to achieve is, to hand over the chosen project-id from the portal to the BSP - iView.

request->get_cookies provides me with the cookie "sap-appcontext", which I think contains the portal session-id. Since BSP has it's own session-id, I somehow have to get the session - content of the portal, where I hope, the chosen project-id is stored.

Am I on the right way?

I would appreciate any help or suggestions.

Thanks in advance.

Daniel
