The sample CGI programs we will look at in class are here. Each directory holds a complete example CGI program and (in most cases) an HTML page that will invoke the CGI program. See the README files for more details.

• isindex: shows how to use an ISINDEX tag with a CGI program.
• getgrades: simple form handling CGI program.
• getfile: shows how to use a file selection field, the browser submits the contents of a file to the CGI program.
• javascript: same CGI program as getgrades, but now the form includes some Javascript code for validating the fields before submission.
• pizza: A Pizza ordering system that uses a single CGI program to handle multiple forms, and keeps some state information in hidden form fields.
• simp-cookie: Simple CGI that sets a cookie and prints out all the cookies it got.
• pizzacookie: Same pizza ordering system, but now uses cookie so you don't need to log in again.
