using a custom database for persisted SQL Server ASP.Net session state

I am in the process of upgrading a major project from ASP.Net 1.1 to ASP.Net 2.0, and my ideal is to have 2 versions of the web application able to be run so that I can compare what's going on in the .Net 2.0 version to what should go on according to the .Net 1.1 version. This doesn't seem too difficult, just use a different web folder right? Well, this would be the case except that we're using SQL Server persisted session state and although they use a different schema between .Net 1.1 and .Net 2.0, the default database name is the same "ASPState". After a bit of fiddling around I eventually solved the problem.

Step 1 run the following command line from the appropriate .Net 2.0 directory replacing ASPState_2_0 with the database name you wish to use

aspnet_regsql -S localhost -E -ssa
dd -sstype c -d ASPState_2_0

This creates the session state database with the appropriate schema in the specified database name instead of the default.

Step 2 modify the following line in the web.config file accordingly

<sessionState mode="SQLServer" allowCustomSqlDatabase="true" stateConnectionString="tcpip=" sqlConnectionString="data source=localhost;Initial Catalog=ASPState_2_0;Trusted_Connection=Yes;" cookieless="false" timeout="15" />

Step 3 Manually give the ASPNet user (or whatever user you are running the ASP.Net web application as the appropriate priviledges on the database tables in the newly created session state databse.

    nice1, going to use this in a live system next week. we've had the two versions of .net working off the same one for ages with no problems but i like the idea of splitting them. it also would allow for better tuning if needs be
