+<h2><a name="errordocs" id="errordocs">Filtering and Response Status</a></h2>
+ <p>mod_filter normally only runs filters on responses with
+ HTTP status 200 (OK). If you want to filter documents with
+ other response statuses, you can set the <var>filter-errordocs</var>
+ environment variable, and it will work on all responses
+ regardless of status. To refine this further, you can use
+ expression conditions with <code class="directive">FilterProvider</code>.</p>
