     <p>
+      In online mode, link checker's output should not be buffered to avoid
+      browser timeouts.  The link checker itself does not buffer its output,
+      but in some cases output buffering needs to be explicitly disabled for
+      it in the web server running it.  One such case is Apache's mod_deflate
+      compression module which as a side effect results in output buffering;
+      one way to disable it for the link checker (while leaving it enabled for
+      other resources if configured so elsewhere) is to add the following
+      section to an appropriate place in the Apache configuration (assuming the
+      link checker script's filename is <code>checklink</code>):
+    </p>
+
+    <blockquote><pre>
+&lt;Files checklink&gt;
+    SetEnv no-gzip
+&lt;/Files&gt;
+</pre></blockquote>
+
+    <p>
