Can I use SQL Server Session State with sessions that contain DataTables?

I have inherited an ASP.NET 3.5 application that relies heavily on sessions and storing DataTables within them (I know - bad, bad, bad). The application pool on the remote shared hosting service indicated that memory is at full capacity and as a result customers a开发者_Go百科re losing their shopping carts because of dropped sessions.

Ultimately the goal is to rewrite this code, but for the time being I would like to stabilize the site the best I can. The host has recommended I use SQL Server Session State instead of in-proc. I have no experience with this, so I'm hoping it's as simple as running the .sql against the database to configure SQL Server and updating the web.config.

Any ideas? Thanks.

The docs say only that the session data has to be serializable. AFAIK DataTables are not serializable, unless you do it yourself, which is probably not going to work.
