> Your ISP may have their own page caching system set up to reduce their own traffic. How it would work would be, you go to RinkWorks and load that page and then, when someone else who uses the same ISP loads RinkWorks, the ISP provides that cached copy instead of a fresh copy. But I've never heard of a whole ISP employing such a thing for the very reason that it causes these sorts of problems. I've only really heard of them being used as part of a corporate firewall or something.

That explains a lot.

You see, I have a similar problem when I'm on-line at work. I think our internet server must be set up with a caching system like the one you described, because many times I cannot get new information, such as a forum post that I've just posted, to show up on a page no matter how many times I refresh. Usually if I try again in 20 or 30 minutes, the new post(s) will appear.
