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> </div></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><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></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="directive-section"><h2><a name="AuthDigestAlgorithm" id="AuthDigestAlgorithm">AuthDigestAlgorithm</a> <a name="authdigestalgorithm" id="authdigestalgorithm">Directive</a></h2><table class="directive"><tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Selects the algorithm used to calculate the challenge andresponse hashes in digest authentication</td></tr><tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>AuthDigestAlgorithm MD5|MD5-sess</code></td></tr><tr><th><a href="directive-dict.html#Default">Default:</a></th><td><code>AuthDigestAlgorithm MD5</code></td></tr><tr><th><a href="directive-dict.html#Context">Context:</a></th><td>directory, .htaccess</td></tr><tr><th><a href="directive-dict.html#Override">Override:</a></th><td>AuthConfig</td></tr><tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr><tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_auth_digest</td></tr></table> <p>The <code class="directive">AuthDigestAlgorithm</code> directive selects the algorithm used to calculate the challenge and response hashes.</p> <div class="note"> <code>MD5-sess</code> is not correctly implemented yet. </div> </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="directive-section"><h2><a name="AuthDigestDomain" id="AuthDigestDomain">AuthDigestDomain</a> <a name="authdigestdomain" id="authdigestdomain">Directive</a></h2><table class="directive"><tr><th><a href="directive-dict.html#Description">Description:</a></th><td>URIs that are in the same protection space for digestauthentication</td></tr><tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>AuthDigestDomain <var>URI</var> [<var>URI</var>] ...</code></td></tr><tr><th><a href="directive-dict.html#Context">Context:</a></th><td>directory, .htaccess</td></tr><tr><th><a href="directive-dict.html#Override">Override:</a></th><td>AuthConfig</td></tr><tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr><tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_auth_digest</td></tr>⌨️ 快捷键说明
