I can't get iWeb to STOP working.

Question

I uploaded a published iWeb site to my existing web server, under a add-on domain. It was accessible through http://mydomain.com/Photos.html
I noticed after doing this, though, that going to http://mydomain.com/ automatically loaded the iWeb page by default, not the index.php file there. So my domain would go to http://mydomain.com/Photos.html by default instead.
But I deleted everything from that directory — completely empty — but yet I still get a redirect to http://mydomain.com/Photos.html. Even though it doesn't exist!!!
The most frustrating part is this: when you reload that page— the browser acknowledges that it's no longer there, e.g. 404 Not Found.
So how is it that the page comes up in the first place? Where is the data from this page coming from, if I've deleted it from the directory, cleared my cache, loggedout and restarted my computer? And if it exists somewhere, then why then when I refresh the same URL does it come up as a 404?
I can't make heads or tails of this and right now I'm blaming Apple and iWeb for this stubborn behavior because I can delete/add files from other domains/parts of my site and they will break/work as you would expect.
What did iWeb do to make this happen? How I can STOP iWeb's silly page from loading!?

Answer 1

Okay, I figured it out.
I would clear the cache while the page was still being viewed in a window, and for some reason that didn't actually clear the cache. So that's the browser's being a good little browser, but it's annoying because it should clear everything.
iWeb also has a problem in that is tells pages to cache forever, so the browsers are only doing what they're told.
Close the window, clear the cache, good to go.
