CGI is the assignment of responsibilities for HTTP server and CGI scripts in response to client requests.

Customer requests are by URL, method, and ancillary information about the transport protocol,

CGI defines some abstract parameters used to describe the request from the client, and defines the programming interface between the HTTP server and the script.

The server-side responsibility is to manage connections, data transformations, transmissions, network problems associated with client requests,

Then the client is responsible for the client's problems, such as data access, document processing.
