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.

• getgrades: simple form handling 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.
• showcookies: Simple CGI that and prints out all the cookies it got and sends back a form that can be used to tell the CGI to set a cookie
• pizzacookie: Same pizza ordering system, but now uses cookie so you don't need to log in again.
