+    <p>Specifying a level without a module name will reset the level

+    use the module source file name, the module identifier, or the
+    module identifier with the trailing <code>_module</code> ommited
+    as module specification. This means the following three specifications
+    are equivalent:</p>

+      LogLevel info ssl:warn<br />
+      LogLevel info mod_ssl.c:warn<br />
+      LogLevel info ssl_module:warn<br />

+    <p>It is also possible to change the level per directory:</p>

+        LogLevel info<br />
+        &lt;Directory /usr/local/apache/htdocs/app&gt;<br />

+
+    <note>
+        Per directory loglevel configuration only affects messages that are
+	logged after the request has been parsed and that are associated with
+	the request. Log messages which are associated with the connection or
+	the server are not affected.
