title: RewriteRule to extract an optional time parameter
body: <p>can anybody help me to make the following URLs functioning:</p>
  
  <pre><code>localhost/v/KmV9ffyC2kA
  localhost/v/KmV9ffyC2kA?t=3m2s
  </code></pre>
  
  <p>I don't really know why this RewriteRule isn't working:</p>
  
  <pre><code>RewriteRule ^v/(.*)\??t=(.*)$    index.php?v=$1&amp;t=$2 [R]
  </code></pre>
  
  <p>Thanks a lot!</p>
