Hi,

There are some usefull environment variables, like

PATH_INFO
PATH_TRANSLATED
DOCUMENT_ROOT
SCRIPT_NAME

Notice, it depends for which httpd server you are creating the ISAPI extension DLL, because not all server set all variables correct.

PWS sends always the WWW server document root, the real path, in the environment variable PATH_TRANSLATED.

The path i want to find out has nothing with the path to where the script is. The querystring may contain :
www.myserver.com/script/myscript?dir=/chr/guestbook
Then I want to find out the real path for /chr/guestbook, with PWS i have found out that i saves the homedir and virtuals path in the registry, dos IIS this.

(Sorry my bad english)

Why do you use this (?)

www.myserver.com/script/myscript/chr/guestbook

because the term /chr/guestbook is an extra path and  can be found in the PATH_INFO variable and then PATH_TRANSLATED gives you the correct "real" path on your server.

example:

www.myserver.com/scripts/test.dll/wwwroot/test.html

the variables have the following content
PATH_INFO = /wwwroot/test.html
PATH_TRANSLATED = c.\webshare\wwwroot\test.html

I think IIS stores also anything in the registry, but I don't know it exactly and you shouldn't use the registry to find out where your file is located!!

May be, this is what you need.

Use an extra path, as I discripted in my las comment, like this

www.myserver.com/scripts/myscript.dll/chr/guestbook

then you'll find in the environment variables the following content

PATH_INFO = /chr/guestbook
PATH_TRANSLATED = drive:\path to the file\and the file itself

If you need more details, contact me - bye

Well, I want to know the real path to a directory, you can't do that with that. With that you show me you need a file.
