What is the common gate interface?
In computers, several things can be taken, including a node that physically connects diverse networks, converts their protocols to communicate, or a functional service provided by the intermediary between multiple systems. Gateway programs can act as gates between sources on the server-like side are database-a web. The Common Gateway (CGI) interface was an initial mechanism that served as a general interface between the server and these server programs, and most servers were used to process client requirements that required data processing on the server side. It is a standard and also an interface.
The common interface of the gate works in two directions. Suppose the user sends a request via a web browser, such as sending the HTML form with data to be added to the addressees list. The HTTP server can only serve documents, not process data. So once http (hypertext transmission protocol) to the IS server complete, Common Gate interfaceWay transmits data from the server to Gateway program, which connects to the database. Processing results, such as a confirmation message, are returned to a user who travels along the way: from the database to the gateway through the common gateway interface to the server via HTTP to the user's web browser.
Script of the common Gateway interface is the name of the software program that has been used to process the query into the database. It had the advantage that the operating system was agnostic, which means it would work on the server, regardless of which operating system was running. While CGI has been used a lot in the first days of the website, there are now newer and more efficient methods on the side of the queer processing server, and these are now also found. These include ASP (Active Server Page) and its newer version of ASP.NET (active page for Dot-Net, also known as ASP+) and JSP® (Javasever Page) that allows CombinacI HTML (Hypertext Markup Language) and Java work smoothly on one website, but note that ASP is made by Microsoft® and runs only on Microsoft® websites.
CGI has also evolved. Fastcgi ™, open standard, language independent CGI expansion that allows distributed computer technology to A-Na difference from CGI-noes to completion of each requirement, but is waiting for another request. SCGI (Simple CGI) is another alternative, both the protocol and the program, located in the public sphere.
