aliasncnu wrote Hi, DNN Login module provide a the return back to source page if you Logout from pages other than homepages. But this becomes a problem when I use Session. Let me explain clearly. I have developed a module where Session are widely used if users click logout without closing browsers, waiting for a long time exceeding Session Timeout to login again. They will met the expetions due to Session["someobject"] becoming null, which should be initialize in other pages or modules. So I hope DNN provide a setting to let site managers cancel the return-back-to-source-url functionality. Or if you someone got similar scenarios like this, please share your solution. Thanks a million. Ricky.

Are you saying that, without custom code - this scenario exists?  If so - it sounds like a bug in the core that should be fixed.  If the problem is caused by custom code - why can't you check to see if the session is nothing before using stored objects?
