ABSTRACT
A Web application is a network application involving a hypertext transfer protocol (HTTP) server and HTTP clients. Internet Explorer is a common HTTP client software package for the Windows environment. Internet information server (IIS) is a common HTTP server software package for the Windows environment. IIS is integrated in Visual Studio 2013. An HTTP server is a software system that hosts and stores Web pages. An HTTP client is a software system that reads and displays Web pages. Hypertext markup language (HTML) is used to construct the appearance of a Web page, while there is program code such as Visual Basic code to provide the back-end functions of a Web page. An HTTP server and an HTTP client work together through request-response cycles. In each request-response cycle, the HTTP client sends a request for an HTML file using universal resource locator (URL) to locate the HTTP server and the HTML file held by the HTTP server, and the HTTP server receives the request and responds to send the requested file to the HTTP client.
