MFC Internet Programming Basics

Microsoft provides many APIs for programming both client and server applications. Many new applications are being written for the Internet, and as technologies, browser capabilities, and security options change, new types of applications will be written. Browsers run on client computers, providing access to the World Wide Web and displaying HTML pages that contain text, graphics, ActiveX controls, and documents. Servers provide FTP, HTTP, and gopher services, and run server extension applications using CGI and ISAPI. Your custom application can retrieve information and provide data on the Internet.

MFC provides classes that support Internet programming. You can use COleControl and CDocObjectServer and related MFC classes to write ActiveX controls and Active documents. You can use MFC classes such as CInternetSession, CFtpConnection, and CAsyncMonikerFile to retrieve files and information using Internet protocols such as FTP, HTTP, and gopher. You can use CHttpServer and CHttpFilter and related MFC ISAPI classes to extend Web servers with custom applications and filters.
