    <p><code class="directive">AuthDigestNonceLifetime</code>指令控制服务器nonce(当前值)的有效秒数。当客户端连接服务器时使用了一个过期的nonce(当前值)，服务器将返回一个带有"<code>stale=true</code>"的401错误(要求重新认证)。如果<var>seconds</var>小于等于"0"，那么nonce(当前值)将永远不会过期(强烈反对这么做)。一般这个值应当在30到120之间比较合理(最好不要小于10)。</p>

    <p><code class="directive">AuthDigestProvider</code>指令设置了该区域的(摘要)认证支持者(Provider)。默认的<code>file</code>支持者由<code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code>模块实现。必须确保所需的认证支持模块存在于服务器中(静态连接或DSO)。</p>

    <p>能够提供认证支持者(Provider)的模块如下：<code class="module"><a href="../mod/mod_authn_dbm.html">mod_authn_dbm</a></code>和<code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> 。</p>

    <p><code class="directive">AuthDigestQop</code>指令用于指定使用那个级别的<dfn>保护质量(quality-of-protection)</dfn>。<code>auth</code>将只进行认证(用户名/密码)；<code>auth-int</code>除了认证以外还进行完整性校验(实体的MD5值将被计算和检查)；<code>none</code>将使用旧的RFC-2069摘要算法(不包含完整性检查)；<code>auth</code>和<code>auth-int</code>可以同时指定，在这种情况下，浏览器将会自己选择使用哪种一种。<code>none</code>不推荐使用。</p>

    <p><code class="directive">AuthDigestShmemSize</code>指令指定了服务器启动时为了跟踪客户端而分配的共享内存字节数。注意，这个共享内存段不能设置为小于只跟踪<em>一个</em>客户端所需要的最小内存数量，这个最小数量取决于你的系统。如果你想知道这个最小值，你只要将<code class="directive">AuthDigestShmemSize</code>设为"<code>0</code>"，然后读取重启Apache时返回的错误信息即可。</p>

    <p><var>size</var>通常按照字节计算，但是可以通过加上后缀"<code>K</code>"或"<code>M</code>"来按照KB或MB计算。比如，以下写法都是一样的：</p>

    <div class="example"><p><code>
      AuthDigestShmemSize 1048576<br />
      AuthDigestShmemSize 1024K<br />
      AuthDigestShmemSize 1M
    </code></p></div>
