I have a web sitre which users log into using an ASP page which verifies their details against a SQL database.
We now want to include a number of Excel spreadsheets onto the web site, but control which users can access which spreadsheets.
We will provide direct access to their permitted spreadsheets by providing the necessary hyperlinks on the web pages we deliver, but how do we stop them accessing an Excel sheet they are not supposed to view.
I do not want them to have to provide an NTFS user name and password if at all possible - we already know who they are through their previous logon.
Thanks in advance.
