Elements and Performance Criteria

1. Define specification for CGI script

   • Define the functionality of the CGI script
   • Choose appropriate language in which to write the CGI script
   • Determine server requirements
2. Create CGI form and write script

3. Test CGI script
   • Configure the server, if required, that will host the CGI script
   • Upload the CGI script to the server
   • Run the CGI form and assess its output
   • Reiterate until the specification for the CGI script is met
