Apache/PHP URL problem

Just noticed a strange problem with one of my business servers. It's configured identically (afaik) to all of my other servers (which do not exhibit this behavior), with Apache 1.3.20 and PHP 4.0.6, running on Linux Mandrake 7.2. The problem occurs only when requesting PHP documents. Say, for example, I have a PHP script at: http://www.example.com/myphpscript.php For some reason, I can also access this page via: http://www.example.com/myphpscript On top of that, I seem to be able to pass a whole bogus path afterwards: http://www.example.com/myphpscript/blah/blah/blah/and/so/on/etc/ ...and the page (myphpscript.php) is still displayed properly. It's not really a big deal, but I had some prick with too much time on his hands taking advantage of this, filling my logfiles with thousands of requests for ~300-character URLs. This ONLY happens with files with the .php extension (not .html files) so I'm not sure if it's a problem with my Apache config, my PHP config, or what... Anyone have any clues? I've been through both the Apache and PHP docs a few times over, but can't seem to find anything relevant. Compiled Apache with: --prefix=/usr/local/apache --enable-module=ssl --enable-module=so --enable-m odule=log_agent --enable-module=log_referer --enable-module=proxy --enable-m odule=rewrite --enable-module=speling --enable-module=usertrack --enable-mod ule=vhost_alias And PHP with: --with-apxs=/usr/local/apache/bin/apxs --enable-versioning --with-mysql=/usr /local/mysql --enable-track-vars Any help would be appreciated!
