CGI stands for common gateway interface. CGI is required in order for information passed from the client to the server using HTTP to be processed by a program which is running on the server. CGI is a defined standard that provides for the passing of data between a web server and a CGI application. The CGI defines a set of environment variables that are used to pass the data. A CGI application may be written in C, C++, Perl, Unix shells, TCL, JAVA, visual basic or other languages. The CGI variables may be set on the client side using client side embedded script code such as JAVA script or VB script.
