    <p>Digest authentication is more secure than Basic authentication,

    but only works with supporting browsers. As of September 2004, major

    browsers that support digest authentication include <a href="http://www.w3.org/Amaya/">Amaya</a>, <a href="http://konqueror.kde.org/">Konqueror</a>, <a href="http://www.microsoft.com/windows/ie/">MS Internet Explorer</a>

    for Mac OS X and Windows (although the Windows version fails when

    used with a query string -- see "<a href="#msie">Working with MS

    Internet Explorer</a>" below for a workaround), <a href="http://www.mozilla.org">Mozilla</a>, <a href="http://channels.netscape.com/ns/browsers/download.jsp">

    Netscape</a> 7, <a href="http://www.opera.com/">Opera</a>, and <a href="http://www.apple.com/safari/">Safari</a>. <a href="http://lynx.isc.org/">lynx</a> does <strong>not</strong>

    support digest authentication. Since digest authentication is not as

    widely implemented as basic authentication, you should use it only

    in environments where all users will have supporting browsers.</p>

    but only works with supporting browsers. As of this writing (December

    2012) all major browsers support digest authentication.</p>

<h2><a name="msie" id="msie">Working with MS Internet Explorer</a></h2>

    <p>The Digest authentication implementation in previous Internet

    Explorer for Windows versions (5 and 6) had issues, namely that

    <code>GET</code> requests with a query string were not RFC compliant.

    There are a few ways to work around this issue.</p>

    <p>

    The first way is to use <code>POST</code> requests instead of

    <code>GET</code> requests to pass data to your program.  This method

    is the simplest approach if your application can work with this

    limitation.

    </p>

    <p>Since version 2.0.51 Apache also provides a workaround in the

    <code>AuthDigestEnableQueryStringHack</code> environment variable.

    If <code>AuthDigestEnableQueryStringHack</code> is set for the

    request, Apache will take steps to work around the MSIE bug and

    remove the query string from the digest comparison.  Using this

    method would look similar to the following.</p>

    <div class="example"><h3>Using Digest Authentication with MSIE:</h3><p><code>

    BrowserMatch "MSIE" AuthDigestEnableQueryStringHack=On

    </code></p></div>

    <p>This workaround is not necessary for MSIE 7, though enabling it does

    not cause any compatibility issues or significant overhead.</p>

    <p>See the <code class="directive"><a href="../mod/mod_setenvif.html#browsermatch">BrowserMatch</a></code>

    directive for more details on conditionally setting environment

    variables.</p>
