Sessionstate mode =SQLServer

I have in web-config:     <sessionState  mode="sql server"  ..>

I tried the code below but line { string cookieHeader = Request.Headers["Cookie"]; }

gives me an Error. Is it related to the fact that sessionState  mode is Sql server??

If so how can I modify the below code to check if session is expired when sessionState  mode="sql server" ??

I found the below info at http://forums.asp.net/t/1138444.aspx. It shows how to check if session is expired

protected void Page_Load()
{
   if (Context.Session != null)

   {
      if (Session.IsNewSession)
      {
         string cookieHeader = Request.Headers["Cookie"];

         if ((null != cookieHeader) && (cookieHeader.IndexOf("ASP.NET_SessionId") >= 0))

         {
            Response.Redirect("sessionTimeout.htm");
         }
      }
   }
}

Thanks

And did you try it?

What error do you get ? I don't think you can catch the "session expired"


Session_End doesn't fire in SQL Server session state mode.

For clearing the expired session data: SQL Server Agent needs to be running. It runs a
stored proc every minute which gets rid of expired session data

Yes I tried this code. I did debug it also.  It does Not give an error (sorry for the unclear statement in my original question).

The expression { null != cookieHeader } returns true;

but cookieHeader.IndexOf("ASP.NET_SessionId") returns -1 ..so

(null != cookieHeader) && (cookieHeader.IndexOf("ASP.NET_SessionId") >= 0) returns false

and line Response.Redirect("sessionTimeout.htm") never executed.

How can I modify the code to check if session is expired when sessionState  mode="sql server" ??

Thanks

I think you can remove the

if ((null != cookieHeader) && (cookieHeader.IndexOf("ASP.NET_SessionId") >= 0))

condition and see if it redirects correctly.
