env vars problem

Hi, I'm in trouble using variables written directly on the request url by the client ... I mean: I'm trying to implement on my web space in hosting (php 3.0.16 as cgi + apache on *nix box) a simply method to pass variables using mod_rewrite with url like this: http://myhost/var1/var2/etc/index.php3 ... The problem is that I've not idea how to get the piece of request uri between http://myhost and index.php3 (/var1/var2/etc/) because I don't see nothing that I could use (on my local box I use REQUEST_URI) ... I've tryed to printout a phpinfo() calling http://myhost/var1/var2/etc/index.php3, but nothing seems available ... e.g. REDIRECT_URL /index.php3 SCRIPT_FILENAME /www/myhost/cgi-bin/php SCRIPT_NAME /cgi-bin/php PATH_INFO /index.php3 PATH_TRANSLATED /www/myhost/index.php3 Any suggestion or ideas are very welcome. Many thanks in advance. max
