The CGI program parses the input from the server and performs any number of computing and data access functions:
  • looking up information in files on the server or in server databases.
  • performing computions or communicating with other machines.
  • returning already prepared documents or other multimedia files.
  • returning a document prepared "on-the-fly"
When the CGI program terminates, the server closes the connection.
