TSGL: IE refresh latency--explanation?

I think I've figured out what's happening, thanks to your many and varied
suggestions.
When any web page is called up by a viewer, it remains in the host's cache
for a certain number of hours before it gets deleted.
This would, I think, explain why the ftp software shows the newly-loaded
page ("View source") on the host but the browser is downloading the old
page from the cache. If I "view source" on the downloaded page in browser,
it shows the old coding.
I tried Will's idea of deleting the page before re-loading it, but that
didn't make any difference. Nor would I expect it to if my explanation is
correct, as the old page would remain in the server cache.
Does that sound logical?
It's a darned nuisance when you're in the middle of refreshing a website,
as you can't check your results until next day. But it does result in
almost instant downloads of each page.
Do all web hosts work that way I wonder?
Another possibility I guess is that my ISP caches all web pages for a
certain time, though that wouldn't make a lot of sense as it would
effectively disable the refresh button.
