    Problem with sessions (Object reference not set to an instance of an object.) on root node

    I've added a usercontrol to the master template which displays information based on a session.

    When trying to access the root node of my site I get a "Object reference not set to an instance of an object." error. This only occurs when accessing www.mysite.com and not when accessing www.mysite.com/home.aspx which are both the same page.

    Just to make sure the problem is related to the session I have only included the following line in the Page_Load of my usercontrol.

    Response.Write(HttpContext.Current.Session.Count.ToString());

    And it results in the "Object reference..." error. Anyone have a clue why this happens? What's different from loading mysite.com and mysite.com/home.aspx when they both should return the same node?

    Have you added runAllManagedModulesForAllRequests="True" to the system.webServer/modules section in web.config?

    <modules runAllManagedModulesForAllRequests="True">

    Best

    I second the request for an explaination of this behavior. It solved some major woes I was having with membership and member login issues!

    Same for me! So, what's the trick ;-)?

    I believe I learned it from this post: http://our.umbraco.org/forum/developers/extending-umbraco/4433-Accessing-Session-State-in-User-Control

    When i did this it completely bugged out my umbraco ?

    unable to save - said duplicate template.
    and i decided to restart umbraco - unable to start it.

    i removed the
          <modules runAllManagedModulesForAllRequests="True">

    and it worked again - of course i still have the error with object reference.
