I saw your post, and was wondering if you had made any progress on a solution. It seems like a nice DNN Extension to provide for some functionality like what I see from the following link, which just describes a database-based approach to managing Session data. I do like your thoughts on tying this back to the aspnet membership functionality.

@Chuck Miller:

I am so sorry I never responded to your post...I never got a notification that someone replied to my thread until today (by Lucas Jans' post). No I never ended up getting a clean solution to this. I basically fudged it by placing code in each of my page's load method that updated a value in the DB with the current DateTime. Before each update, I would check the last stamp, and if the last stamp exceeded a certain "timeout" value (ie: equal to the DNN timeout value) I would assume the use logged out and back in. It works in "most" cases, as long as the person stayed in my module. If a user was bouncing around in other pages outside of my module...well...that could be an issue since the timestamp would not be updating properly. ::Shrugs:: Basically you have to jump through hoops right now in code. I have also used the DNN Caching methods, placing information in the cache with a relatively short TTL window, which helps insure that the data expires and gets removed.

@Lucas Jans:

I appreciate your input, however when you are developing a module, you do not have control over a customers server setup. If they setup their server farm to share Session States across servers, you are fine, if they didn't, you have a problem. I never said it wasn't possible to set up a farm to share session variables. As a developer, we can't assume environments would be set up correctly. Maybe the clients has a reason to not set it up, who knows. As such, I was trying to determine at the time, the best course of action to handle this. Saving the information to the DB with an expiration is the only method that I have found.
