Even more likely than a 404, would be 302. *Some* CMS's return 302
status codes for URLs that 'don't exist' and redirect you to like the
home page or a search page or something. A 302 is NOT an error, it is
just a redirection to someplace else, therefor a URL fopen wouldn't
fail, it would open whatever the URL on Location: header pointed to.
