I have a website which uses the custom 404 error handling in PHP/Apache to display specific pages.
e.g. http://metachat.org/recent

I’ve a feeling this is a bad way of doing this, but it’s code I inherited…

Although the page displays correctly on most browsers, I’m getting a situation where AVG Anti-Virus is hijacking the page and redirecting it to an offsite 404 page.

I’ve tried to force a header (Status: 200 OK) using the header command in PHP, but if I do a curl -I of the page, I get the following…

HTTP/1.1 404 Not Found Date: Fri, 03 Oct 2008 11:43:01 GMT Server: Apache/2.0.54 (Debian GNU/Linux) DAV/2 SVN/1.1.4 PHP/4.3.10-16 mod_ssl/2 .0.54 OpenSSL/0.9.7e X-Powered-By: PHP/4.3.10-16 Status: 200 OK Content-Type: text/html

I guess that first line is the line AVG traps for its forced redirect. Without rewriting the software to use Mod_rewrite (which I don’t really understand), how can I (in PHP) stop the ‘HTTP:/1/1 404 Not Found’ line being sent in the headers when displaying this page?

Thanks.

  1. There’s no way other than using URL rewriting (mod_rewrite) or creating the missing pages. What’s happening is that the client requests a page which doesn’t exist. Apache is configured to serve a special page upon 404 errors, but it still sends the 404 status code, then AVG traps that.

    So, you could do something like:

    RewriteEngine On RewriteCond %{REQUEST_URI} !-f RewriteCond %{REQUEST_URI} !-d RewriteRule (.*) index.php?missing_content=$1

    That will rewrite everything that doesn’t exist (and would thus give a 404) to your index.php with the URL path in the missing_content query string parameter
