+<h2><a name="env" id="env">Environment Variables</a></h2>
+    <p>In addition to the configuration directives that control the
+    behaviour of <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>, there are a number of
+    <dfn>environment variables</dfn> that control the FCGI protocol
+    provider:</p>
+    <dl>
+        <dt>proxy-fcgi-pathinfo</dt>
+        <dd>By default <code class="module"><a href="../mod/mod_proxy_fcgi.html">mod_proxy_fcgi</a></code> will neither create
+        nor export the <var>PATH_INFO</var> environment variable. This allows
+        the backend FCGI server to correctly determine <var>SCRIPT_NAME</var>
+        and <var>Script-URI</var> and be compliant with RFC 3875 section 3.3.
+        If instead you need <code class="module"><a href="../mod/mod_proxy_fcgi.html">mod_proxy_fcgi</a></code> to generate
+        a "best guess" for <var>PATH_INFO</var>, set this env-var.
+        This is a workaround for a bug in some FCGI implementations.</dd>
