title: Single RewriteRule to create a redirection with two conditions
body: <p>I found this rule which works fine with just one condition which is: <code>foobar</code> is in the string.</p>
  <p>I need to change this to include a new condition to have two conditions (instead of one):</p>
  <ul>
  <li><p><code>foobar</code> is in the string. This is already working.</p>
  </li>
  <li><p><code>meetball</code> is NOT in the string.</p>
  <pre><code>RewriteRule ^(.*)foobar(.*)$ http://www.example.com/index.php [L,R=301]
  </code></pre>
  </li>
  </ul>
