C++ Web Programming (JNNC Technologies)

In the earlier chapters of C++, you have learned about the basics of various syntax and way of writing C++ programs for building applications and programs. In this chapter, you will get a new taste of linking web with your C++ program. For this you need to have knowledge of basics of CGI and how it works

What is CGI?

CGI stands for Common Gateway Interface is a set of standards that defines how information is exchanged from web server, passing the web user’s request to an application program and to receive data back to user. When any user requests for a web page, the server sends back the requested page. 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) and is part of the Web’s Hypertext Transfer Protocol (HTTP).
