CGI define
The common gateway interface (CGI) is a standard way for a Web server to pass a Web user's request to an application program and to receive data back to forward to the user.n alternative to a CGI application is Microsoft's Active Server Page (ASP), in which a script embedded in a Web page is executed at the server before the page is sent. Abbreviation of Common Gateway Interface, CGI is a specification for transferring information between a World Wide Web server and a CGI program. A CGI program is any program designed to accept and return data that conforms to the CGI specification.The program could be written in any programming language, including C, Perl, Java, or Visual Basic.hese technologies are known collectively as client-side solutions, while the use of CGI is a server-side solution because the processing occurs on the Web server. One problem with CGI is that each time a CGI script is executed, a new process is started. For busy Web sites, this can slow down the server noticeably. Common Gateway Interface (CGI) is a standard environment for web servers to interface with executable programs installed on a server that generate web pages dynamically.he CGI system also allows the Web browser to send information to the script via the URL or an HTTP POST request. If a slash and additional directory name(s) are appended to the URL immediately after the name of the script, then that path is stored in the PATH_INFO environment variable before the script is called. CGI has two different meanings: 1) Common Gateway Interface, and 2) Computer Generated Imagery. 1) Common Gateway Interface. The Common Gateway Interface (CGI) is a set of rules for running scripts and programs on a Web server.It specifies what information is communicated between the Web server and clients' Web browsers and how the information is transmitted.his type of CGI refers to 3D graphics used in film, TV, and other types of visual media. Most modern action films include at least some CGI for special effects, while other movies, such as a Pixar animated films, are built completely from computer generated graphics. The Web server typically passes the form information to a small application program that processes the data and may send back a confirmation message. This method or convention for passing data back and forth between the server and the application is called the common gateway interface (CGI).It is part of the Web's Hypertext Transfer Protocol (HTTP).n alternative to a CGI application is Microsoft's Active Server Page (ASP), in which a script embedded in a Web page is executed at the server before the page is sent. Many HTML pages that contain forms, for example, use a CGI program to process the form's data once it's submitted. Another increasingly common way to provide dynamic feedback for Web users is to include scripts or programs that run on the user's machine rather than the Web server.These programs can be Java applets, Java scripts, or ActiveX controls.hese technologies are known collectively as client-side solutions, while the use of CGI is a server-side solution because the processing occurs on the Web server. One problem with CGI is that each time a CGI script is executed, a new process is started. For busy Web sites, this can slow down the server noticeably. When the user requests a Web page (for example, by clicking on a highlighted word or entering a Web site address), the server sends back the requested page. However, when a user fills out a form on a Web page and sends it in, it usually needs to be processed by an application program.n alternative to a CGI application is Microsoft's Active Server Page (ASP), in which a script embedded in a Web page is executed at the server before the page is sent. Computer-generated imagery (CGI) is the application of computer graphics to create or contribute to images in art, printed media, video games, films, television programs, commercials, videos, and simulators.he visual scenes may be dynamic or static, and may be two-dimensional (2D), though the term CGI is most commonly used to refer to 3D computer graphics used for creating scenes or special effects in films and television. In order for the user to receive the newsletter, he must fill out a CGI form with all of his applicable information. The form is then sent to the server using CGI, and the server processes the information that was sent in the form in order to add the user to its database and initiate the user's newsletter service.he form is then sent to the server using CGI, and the server processes the information that was sent in the form in order to add the user to its database and initiate the user's newsletter service. Main » TERM » C ». A CGI form is a way for an Internet user to interact dynamically with a Web server. An HTML page that contains a form may use a CGI program to process the form's data once it has been submitted.he form is then sent to the server using CGI, and the server processes the information that was sent in the form in order to add the user to its database and initiate the user's newsletter service.
