53329 Posted September 3, 2008 Share Posted September 3, 2008 Whenever I output 404 headers it shows a blank page in Firefox but my IE processes the 404 like normal. I'm not sure if its just Firefox, addons, or my code. Here are a few I tried... header("HTTP/1.0 404 Not Found"); header("Status: 404 Not Found"); header(' ', true, 404); All result in a blank page. I'm using firefox 3.0.1 and the only addons I have are Web Developer and StumleUpon so I doubt it that. I'm completely dumbfounded. Quote Link to comment Share on other sites More sharing options...
53329 Posted September 3, 2008 Author Share Posted September 3, 2008 Sorry to double post. IE will generate a 404 page now if its a URL that I haven't been to (even just changing get vars). Otherwise I can clear cache and get the same blank page as Firefox. Firefox to clarify seems to just ignore the 404 header completely.

dis Posted September 5, 2008 Share Posted September 5, 2008 I find the exact same issue. However, I work around it. Best way, is to echo out a custom PHP file, for Firefox. If you want IE to show the same as Firefox, your file will need to be larger than 512 bytes. <?php header('HTTP/1.0 404 Not Found'); include(_DIR.'includes/404.php'); exit(); ?> <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>404 Not Found</title> </head><body> <h1>Not Found</h1> <p>The requested URL '<strong><?php echo $_SERVER['REQUEST_URI']; ?></strong>' was not found on this server.</p> </body></html> <!-- - Unfortunately, Microsoft has added a clever new - "feature" to Internet Explorer. If the text of - an error's message is "too small", specifically - less than 512 bytes, Internet Explorer returns - its own error message. You can turn that off, - but it's pretty tricky to find switch called - "smart error messages". That means, of course, - that short error messages are censored by default. - IIS always returns error messages that are long - enough to make Internet Explorer happy. The - workaround is pretty simple: pad the error - message with a big comment like this to push it - over the five hundred and twelve bytes minimum. - Of course, that's exactly what you're reading - right now. --> Quote Link to comment Share on other sites More sharing options...
