    <p>Using MD5 Digest authentication is very simple. Simply set

    up authentication normally, using <code>AuthType Digest</code> and

    <directive module="mod_auth_digest">AuthDigestProvider</directive>

    instead of the normal <code>AuthType Basic</code> and

    <p>To use MD5 Digest authentication, simply 

    change the normal <code>AuthType Basic</code> and

    <directive module="mod_auth_basic">AuthBasicProvider</directive>.

    Then add a <directive module="mod_auth_digest"

    to <code>AuthType Digest</code> and

    <directive module="mod_auth_digest">AuthDigestProvider</directive>,

    when setting up authentication, then add a 

    <directive module="mod_auth_digest"

    >AuthDigestDomain</directive> directive containing at least the root

    URI(s) for this protection space.</p>
