+     When running PHP as CGI with IIS, PWS, OmniHTTPD or Xitami, 
+     you MUST set the <link linkend="ini.cgi.force-redirect">
+     cgi.force_redirect</link> directive to <literal>0</literal>.  
+     It defaults to <literal>1</literal> so be sure the directive 
+     isn't commented out (with a <literal>;</literal>).
+    </para>
+    <para>
+     It's important that you're 100% sure that &php.ini; is
+     being read by PHP.  To test this, make a call to
+     <function>phpinfo</function> and near the top will be a
+     listing called <literal>Configuration File (php.ini)</literal>.
+     This will tell you where PHP is looking for &php.ini; and
+     whether or not it's being read.  If just a PATH exists
+     than it's not being read and you should put your &php.ini;
+     there.  If &php.ini; is included with the PATH than it is 
+     being read.
