That sounds like a good idea, but it's a little bit outside anything i've done before... I would be thankful for any help and/or useful links
I found this, but I can't seem to make it work on a cache page. I tried using their "embed" option, instead of the one that puts javascript on the page, but it still doesn't show up on my test cache page.
All of the others I can find require javascript, except for one that uses iframes. But that one doesn't work on a cache page, either.
Don't know if it'll work on a cache page but I wonder if there might be a counter Applet that you could put on the page.
As far as I know, you can't put anything on a cache page other than links and images, not even iframes. Thats why I found the dynamic image idea interesting, but i simply don't know (yet) how to do that I actually saw a hit counter as image on a cache page, but haven't found anyone offering time counters that way...
