web pages work on
contrary to static web pages, which represent technically a simple file on the Web server, sides are also frequently dynamically produced for the moment the requirement. That is meaningful if a web page very current information such as z.B. Stock exchange courses or the weather contained from tomorrow should. In this case the Web server implements a program, which was before specifically developed for this task. It carries the data z. B. from data bases together and the HTML document provides. Thisthen by the Web server to the Browser one transfers and one indicates with the user.

The software thatSearch machine provides a list of suitable on the basis the search word left and produces a web page, which represents this list to the user comfortably.
The possibility of generating web pages dynamically as a function of user inputs and data base contents made the Web fast a universalPlatform for all kinds of applications. The advantages are in independence from operating systems and other characteristics of the Clients. Basic conditions are only a network connection to the server and a Webbrowser.
To generating dynamic web pages each program is applicable, thaton the server system to implement leaves itself. In order to simplify programming, however standards were introduced like the Common gateway interface, in order to make applications of Web also independently of the kind of the Web server. Due to the rapidly rising need according to very efficient serversto the enterprise of applications of Web technologies developed such as PHP, J2EE and .NET.
