Different cache depending on database

[LBandy]

Hi!

Thanks for this great plugin, it is really useful!

My only problem is, that I'm using a survey (the same survey) on every site by default, and I use a database entry based on ip addresses to decide whether or not I should ask the visitor to take the survey. The problem is this: If I take the survey and add the corresponding ip address to the database marking it "filled the survey", on the other site the popup appears again.

Is there a way to make differences between the two kind of visitors depending on a Database entry and not cookies? Maybe is there a way to use the Clear Cache command (appearing on the admin site) in the code, so after the survey had been taken, the whole cache for the specific user should be refreshed?

Waiting for a quick reply, thanks in advance,
