title: .htaccess RewriteRule without URL change in browser
body: <p>I have <code>.htaccess</code> file:</p>
  
  <pre><code>Options +FollowSymlinks
  RewriteEngine on
  RewriteBase /
  
  RewriteCond %{HTTP_HOST} ^somedomain.com [NC]
  RewriteRule ^(.*)$ http://www.somedomain.com/$1 [R=301,NC]
  
  RewriteRule ^r/(.*)$ index.php?rid=$1 [NC]
  </code></pre>
  
  <p>But last condition performs redirect in browser when I request URL like <code>www.somedomain.com/r/123</code> and show me URL like <code>www.somedomain.com/index.php?rid=123</code>. But I need call this script without URL change.</p>
  
  <p>What's wrong?</p>
