                <p>Those that are special to mod_rewrite include those below.</p>

                <dl>

                  <dt><code>API_VERSION</code></dt>

                  (decoded), unlike most other variables below.</dd>

                </dl>

        </li>

      </ul>

      <code>%{HTTP_HOST}</code>, <code>%{SERVER_PORT}</code>, or

      <code>%{QUERY_STRING}</code> variables respectively.</p>

      <p>In any case, remember that regular expressions are substring

      matches. That is, you don't need the regex to describe the entire

      string, just the part that you wish to match. Thus, using a regex

      of <code>.</code> is often sufficient rather than <code>.*</code>,

      and the regex <code>abc</code> is <strong>not</code> the same as

      <code>^abc$</code>.</p>
