Browsers and "php" extension
I don't get this at all.
I'm using .php extension for all pages on my site. I could open them locally with Opera and Netscape 3. When I tried opening in IE5 it asked me what program to use, I said IE5 and so now when I open a .php page in IE5 it opens in a new instance of IE5. Then I upgraded Netscape to 4.6 and it opens the pages in IE5, too. Opera just opens the page as it would any web page.
What I find even weirder is opening the same pages off the site poses no problems whatsoever.
