I wrote a program called GetPath.asp, which is really no more than to just run server.MapPath("includefile.inc") that then display the results. My website is "ccs2468.com/" so I put http://ccs2468.com/GetPath.asp in the url (I assume that's the root dir) and run it. The result is - E \web\ccs2468com0\htdocs\includefile.inc. Now I'm not sure where the htdocs came from, but I'm pretty sure that would be considered a subdirectory on the root, which there's no such thing, so I took it out.
So now, with my ftp program, I change dirs. to ccs2468.com/books/books.asp and insert this directive -
<!-- #include file="E \web\ccs2468com0\includefile.inc" > and run books.asp. It makes the program crash.
