As per bug 22061, this paragraph predates RedirectMatch, and is thus

        <dt>Solution:</dt>

        <dd>

          <p>We just redirect the URL <code>/</code> to

          <code>/e/www/</code>. While is seems trivial it is

          actually trivial with <module>mod_rewrite</module>, only.

          Because the typical old mechanisms of URL <em>Aliases</em>

          (as provides by <module>mod_alias</module> and friends)

          only used <em>prefix</em> matching. With this you cannot

          do such a redirection because the <directive module="core"

          >DocumentRoot</directive> is a prefix of all URLs. With

          <module>mod_rewrite</module> it is really trivial:</p>

          <p>We redirect the URL <code>/</code> to

          <code>/e/www/</code>:

          </p>

<example><pre>

RewriteEngine on

RewriteRule   <strong>^/$</strong>  /e/www/  [<strong>R</strong>]

</pre></example>

    <p>Note that this can also be handled using the <directive

    module="mod_alias">RedirectMatch</directive> directive:</p>

    <example>

    RedirectMatch ^/$ http://example.com/e/www/

    </example>

        </dd>

      </dl>
