-    <p><code class="module"><a href="../mod/mod_headers.html">mod_headers</a></code> can be applied either early or late
-    in the request.  The normal mode is late, when <em>Request</em> Headers are
-    set immediately before running the content generator and <em>Response</em>
-    Headers just as the response is sent down the wire.  Always use
-    Late mode in an operational server.</p>
-
-    <p>Early mode is designed as a test/debugging aid for developers.
-    Directives defined using the <code>early</code> keyword are set
-    right at the beginning of processing the request.  This means
-    they can be used to simulate different requests and set up test
-    cases, but it also means that headers may be changed at any time
-    by other modules before generating a Response.</p>
-
-    <p>Because early directives are processed before the request path's
-    configuration is traversed, early headers can only be set in a
-    main server or virtual host context.  Early directives cannot depend
-    on a request path, so they will fail in contexts such as
-    <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> or
