Hi all,
     My old application is in classic ASP.
     I am creating new modules in ASP.NET and integrating them with the older version.

     My problem is that I use session variables in both versions.
     But now that Im copying over my global.asax, I get the following error :
-------------------------------------------------------------------------------

Server Error in '/' Application.
--------------------------------------------------------------------------------

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Stack Trace:


[NullReferenceException: Object reference not set to an instance of an object.]
   ToDoList.OverDueList.Page_Load(Object sender, EventArgs e) in c:\inetpub\wwwroot\ToDoList\ToDoList\OverDue.aspx.vb:67
   System.Web.UI.Control.OnLoad(EventArgs e) +67
   System.Web.UI.Control.LoadRecursive() +35
   System.Web.UI.Page.ProcessRequestMain() +731
--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:1.1.4322.573; ASP.NET Version:1.1.4322.573

--------------------------------------------------------------------------------


This runs absolutely fine on my local machine.
The only reason I can think of for this error is because of the global.asa and global.asax clash ?
Am i right ?? How do I solve this ???
Could it be a path issue ? Does the created dll carry the localhost path somewhere in it ?

the .net version and older version can't share session information. you use a commonly available data storage location... ie: database, querystring, cookies, etc.

here's an msdn article on the subject:
