Foil 28 Maintaining State with Hidden Fields

From CGI Programming with Advanced Topics Jackson State University Mississippi -- Fall Semester 97. by Nancy McCracken *
Any application with multiple forms processed by one or more cgi scripts may use hidden fields to pass information from one form to the next.
Typical example is a shopping basket application. The first page can collect user information.
Note that hidden fields are not secret - the user can see them by selecting "View - Document Source".
