title: IE "friendly" HTTP 404 error
body: <p>I know there are some questions similar to this, but none I saw were enough to help...</p>
  
  <p>I have a regular php page which is working absolutely fine in FF and Chrome, but in IE, about 20% of the time, it comes up with a (not-so-)'friendly' HTTP 404 error. When friendly errors are turned off, it works fine too. But my page visitors won't have them turned off...
  I thought it might be because of a mod_rewrite on the page, but even with that turned off and cache deleted the actual page itself is producing the error. It's so strange, because 80% of the time the page loads perfectly fine, but a refresh or a link back to the same page will result in a 404, and then another few refreshes and it's back.
  I don't have access to server logs, because I'm using a 3rd party server and they said there's no logs I can get access to.</p>
  
  <p>Could anyone suggest please what might be causing this problem? Is there a way to see client-side exactly where the 404 came from? Has anyone seen such a thing before - that a page loads sometimes and other times not?</p>
  
  <p>Thanks in advance for any help!</p>
