title: Error 500 when I have RewriteMap in .htaccess
body: <p>I have a map file in this format</p>
  
  <pre><code>233 Alabama/Phenix-City/Ridgebrook
  237 Alabama/Ft.-Mitchell/Riverside-Estates
  </code></pre>
  
  <p>I have the following .htaccess script.  I'm getting a 500 Internal Server Error when the page in question is hit.</p>
  
  <pre><code>RewriteEngine On
  RewriteBase /
  Options +FollowSymLinks
  
  RewriteMap examplemap txt:/var/www/html/site.com/key_pair.txt
  RewriteRule community.php?(.*) ${examplemap:$1} [R]
  </code></pre>
  
  <p>When I pass the following URL I wish for it to be rewritten as follows.</p>
  
  <pre><code>http://example.com/community.php?comm_id=233    
  </code></pre>
  
  <p>should be rewritten like this</p>
  
  <pre><code>http://example.com/Alabama/Phenix-City/Ridgebrook
  </code></pre>
  
  <p>Any thoughts?</p>
