+
+ <p>This module provides a convenient way to set timeouts and minimum data
+ rates for receiving requests. Should a timeout occur or a data rate be
+ to low, the corresponding connection will be closed by the server.</p>
+
+ <p>This is logged at <code class="directive"><a href="../mod/core.html#loglevel">LogLevel</a></code>

+
+ <p>If needed, the <code class="directive"><a href="../mod/core.html#loglevel">LogLevel</a></code> directive
