I'm looking for a good way to visualize ASP.NET session state data stored in SQL server, preferably without creating a throwaway .aspx page.

Does ASP.NET transfer ALL session data from SQL server at the start of a request, or only as needed?

I'm using ASP.NET, with session state stored out of process in SQL Server.

Basically, I have a page t...
