Sharing sessions across applications using the ASP.NET Session State Service

Question

I am trying to share sessions between two web applications, both hosted on the same server. One is a .net 2.0 web forms application the other is as .net 3.5 MVC2 application

Answer 1

I did it this way:

Basically the idea is both apps use native .net sessionState stored in sqlserver. By using the same machine key and making a small tweak to a stored procedure – both apps can share any session keys and/or forms authenication.

Both apps would do something like this in their web.config:

Session state db would need to be set up on a database server, that both apps can see.

Docs for doing this: http://msdn.microsoft.com/en-us/library/ms229862(VS.80).aspx

Command that would need to be run: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin>aspnet_regsql.exe -E -ssadd --sstype p -S .\SQLEXPRESS

Stored procedure (TempGetAppID) tweak to:

 @appId int OUTPUT
AS

    -- start change

    -- Use the application name specified in the connection for the appname if specified
    -- This allows us to share session between sites just by making sure they have the
    -- the same application name in the connection string.
    DECLARE @connStrAppName nvarchar(50)
    SET @connStrAppName = APP_NAME()

    -- .NET SQLClient Data Provider is the default application name for .NET apps
    IF (@connStrAppName <> '.NET SQLClient Data Provider')
        SET @appName = @connStrAppName

    -- end change

SET @appName = LOWER(@appName)
