title: RewriteRule url with a parameter to a new url with same parameter
body: <p>With <code>.htaccess</code> I want to create a URL forwarding from </p>
  
  <ul>
  <li>www.example.com/en/?instance_id=1083&amp;lang</li>
  </ul>
  
  <p>to </p>
  
  <ul>
  <li>www.example.com/en/Veranstaltung/1083/</li>
  </ul>
  
  <p>You can see, that the id is the same, it is possible?
  The "en" in the url may change, it shouldn't be a problem.</p>
  
  <p>I tried some different things, like this:</p>
  
  <pre><code>RewriteEngine on
  RewriteCond %{query_STRING} instance_id=(.*)$$
  RewriteRule ^(.*)$ /$1? [R=301,L]
  </code></pre>
  
  <p>But it didn't work.</p>
  
  <p>I hope, you can help me. I have googled &amp; checked other sites, I haven't been able to find a solution.</p>
  
  <p>If you need more information, only ask me. Its my first question here.</p>

  <p>Added the original links here:</p>
  
  <p><a href="http://dorfbladl.com/en/" rel="nofollow">http://dorfbladl.com/en/</a>   &lt;-- this is the page</p>
  
  <p>If you press one entry of the calendar on the right side, it should be forwarded to</p>
  
  <ul>
  <li><a href="http://dorfbladl.com/en/Veranstaltung/1914/" rel="nofollow">http://dorfbladl.com/en/Veranstaltung/1914/</a></li>
  </ul>
  
  <p>This url is one example, the id changes with every entry.</p>
  
  <p>Maybe it could be useful, to find the solution.</p>
