I have done this without the CGI wrapper, but I think it will work with it as well.you could also have your sys admin make a simlink from httpd/iw-bin to your callserver. That will allow it to be in the lower folder (that you can edit) and still be addressable from iw-binNote, I have not tried that but it should work.
If you do need impersonation, talk to your powers-that-be and tell them they need to give you access to the actual httpd/iw-bin directory.
symlink should still work for that.
Perhaps, but that still requires that the symlink be placed within the httpd/iw-bin directory - which if they had write access to in the first place, they wouldn't need the symlink... ;-)
