hiding .php

hi, i would like to set up a script "forum" such that you can call a url http://www.server.com/forum/general and it will php-parse forum and pass /general as PATH_INFO. it's easy to get done as http://www.server.com/forum.php/general, but i would like to disclose the script name for reasons of obscurity. in fact, i would really like every request to be fed through something like /index.php, where the actual relative URI of the site is passed as PATH_INFO. so something of the form http://www.server.com/url/to/a/page would call /index.php with PATH_INFO=/url/to/a/page, and index.php could take care of whatever needs to be done to display that information. this can easily be done with a 404.php script, but i'd much rather do it transparently without this sort of abuse of the 404 feature. thanks, martin [greetings from the heart of the sun]# echo madduck@!#:1:s@\@@@.net -- "and no one sings me lullabies, and no one makes me close my eyes, and so i throw the windows wide, and call to you across the sky" -- pink floyd, 1971
