In computing , Common Gateway Interface CGI is an interface specification that enables web servers to execute an external program, typically to process user requests. Such programs are often written in a scripting language and are commonly referred to as CGI scripts , but they may include compiled programs. The Web server then launches the CGI script in a new computer process , passing the form data to it.
