Redirecting with 404 doesnt work
<p>I havea code that should redirect in case it doesnt have some request parameter set correctly.</p>

<pre><code>          if(!is_numeric($_GET['id'])){
                         header("HTTP/1.0 404 Not Found");
                    header('Location: '.$url);
                    exit();
               }
</code></pre>

<p>Problem is that whenever I check with Firefoxes plugin, live HTTP headers, I see 302 temporary redirect. why is that? why no 404 response is given?</p>
