PHP 5.

don't tell jerry that...he'll have to admit that my solution works and for
the reasons i expressed why i came up with it - i.e. document_root is tied
to server config. jerry's an old man who only has theory and a lot of time
to live in a theoritical programming environment...and share his
overestimated opinions here. :)

It works just fine. I've got it going on my system here and on a
Windows IIS VPS.

You just have to have PHP installed as an ISAPI app - not a CGI.

BTW - the same it true under Apache, IIRC.
