Saving FBService in Session for Optimization

Dec 7, 2007 at 2:40 PM
Hi,
I have managed to reduce the load time of my IFrame canvas pages significantly by saving the FBService in session and calling CanvasIFrameBasePage.Page_Load only when necessary.
I created my own base class which inherits the CanvasIFrameBasePage, which checks if the service exists in the session and otherwise calls base.Page_Load.
This improves a ton. But I'm worried about session expiration. Since I'm not pretty sure about the session rules, can anyone shed some light on the dangers it imposes and how to avoid them?

Thanks,
Shahar
