Page requires session state error if application open in multiple browsers on same machine
I have an asp.net mobile application and I have found that if you open multiple instances of the application on the same machine (on a desktop node), then the exception "The page requires session state that is no longer available..." is thrown.  It would appear that there is only 1 session cookie per machine.  Perhaps this makes sense because on the actual mobile device you can only have one instance of IE running.  Is there any way to allow for multiple instances of the application.  In other words; can you force unique session cookies?  If not, are there...

Session availability in base page
I've created a base page on a project I'm working on and I'm having all of the pages within the site inherit from it. I'm trying to include all globally needed functionality in it including session management. The problem I'm running in to is that anytime I use session in the base page in its page_load event I end up getting a null reference exception. For instance I've been testing with this bit of code:        HttpContext.Current.Session["test"] = "test";        Response.Write((string)HttpContext.Current.Session["test"])...

Session to hold page state
Hi I am fairly new to ASP.net and I need some advice on how to write a session that will hold a view of a treeview. What I have  are a number of treeviews that are held in panels, and each panel is visible when the user selects the treeview from a dropdown list. However, I want to keep the user selected treeview visible on the page when the user posts back the page when carrying out another action on the page. Unfortunately, I can't use AJAX or any javascript as it is an internal system, and therefore, I would like to try and do this as a session, but I am not sure how I can ...

Unable to make the session state request to the session state server
Hi all, I'm working on the website http://universityauction.net and I was using session variables using InProc session mode to manage session state. This worked fine until I put the website in a load balanced environment, as inproc sessions get lost when jumping from server to server. I decided to move to a state server mode, so I changed my web.config to: <sessionState             mode="StateServer"             stateConnectionString="tcpip=123.456.7.8:42424"      ...
