Signalr: Tracking User State across page requests

I'm trying to implement instant messaging using Signalr in a ASP.NET webforms site.

I have made a good start so far, I can send a message from one client to another without any issue.

My problem comes from maintaining chat windows across asp.net requests.

When a user has a chat window open and navigates to a new page on the site, this counts as a disconnect and new connect to the signalr hub. (Client gets new ConnectionID).

This is a problem as it means I cannot determine weather this is a users first connect (no chat window open, just logged into site) or if they had an active chat window and just changed page.

If they just changed page I would like to keep the chat window open with messages showing. I can reconstruct the conversation from our database, but have no way to know if this conversation should be shown or not.

I have considered using some sort of timeout mechanism (if this conversation was active within the last X minutes, then show it on new page) but this seems to me to be a bit unwieldy.

As I can't save the active conversations in OnDisconnect (as this cannot take any arguments) I would have to use some sort of polling mechanism to save a timestamp of the last time the conversation window was open.

I was wondering has anyone run into any similar problems, and if they have, how did they approach them.

Any help is appriciated...

Found the solution. Use cookies to track the active conversation ID between page requests. Has added benefit of using timeout even if person logs out and then in again within a specified timeframe.

Thanks to cdslnte for triggering the thought...
