Need an idea for the best way to check status of a webpage database

Here's my dilemma, and I'll be happy to pay for good suggestions:

I have a toolbar application that people download and use

while surfing the web.

I also have a database that contains a little data about 100,000 or so webpages.

Whenever someone visits a page that I have data about, I would like my toolbar to flash a green light or something.

But don't worry about how that works. Here's my problem...

What's the most efficient way of knowing if I have data about

a certain page without pinging my database every single time

a person visits a webpage?

If the app hits my database every time a user visits a webpage, and I have 150,000 users, I'm going to be getting 15 million database queries a day, and that's just too much for my poor little server.

There's not enough space in a cookie to store the pages I have information about. I could automatically download a file to the user's harddrive containing the list of webpages I have data about, and the app could just check that, but that would be a pretty big file too.

Maybe there is no easy solution. But I thought I'd post this and let you RAC geniuses think about it.
