help setting iplanet server to parse all files in one directory

I am trying to get one specific directory on an iPlanet 4.1/php 4.3.0 server set up so that all files in the directory are treated as php scripts and executed. Basiucally, I would like php to use the extension .html, but only in one directory. Scripts in the directory execute fine if I use the php extension, but are not parsed if I use html. As directed, my obj.conf has the following: <Object name="x-httpd-php"> ObjectType fn="force-type" type="magnus-internal/x-httpd-php" Service fn="php4_execute" </Object> In the admin server, when I assign the x-httpd-php style to the directory I want, I am immediately taken to the "Edit Style" screen. What, if anything do I need to set there? The install instructions on http://www.php.net/manual/en/install.netscape-enterprise.php do not say. It just say "assign the x-httpd-php style". Do I need to set anything there like file type, defaut query handler, server parsed html, etc? thanks!
