title: What is redirect:// in PATH_TRANSLATED?
body: <p>I have a <strong>.htaccess</strong> rule that passes requests for <strong>/category/category-slug/</strong> to <strong>category.php</strong>. However, when I inspect the <code>$_SERVER</code> super-global, I get this entry:</p>
  
  <pre><code>Array
  (
      [PATH_TRANSLATED] =&gt; redirect://
  )
  </code></pre>
  
  <p>What is that? I’ve never seen <strong>redirect://</strong> before.</p>
  
  <p>This is the relavant <strong>.htaccess</strong> rule:</p>
  
  <pre><code>RewriteRule ^category/([^/]+)/?(.*) /category.php?cat=$1&amp;page=$2 [L,QSA]
  </code></pre>
  
  <p>As a result, I’m not getting <code>$_GET['cat']</code> or <code>$_GET['page']</code> populated in my script as it seems to be coming from a redirect and not having the request being simply re-written. What’s going on?</p>
