An IIS application is a Visual Basic application that uses a combination of HTML and compiled Visual Basic code in a dynamic, browser-based application. An IIS application resides on a Web server, where it receives requests from a browser, runs code associated with the requests, and returns responses to the browser.
In its simplest form, you can use an IIS application to intercept a user request and return an HTML page to the browser. These are just a few of the things you can do with more advanced IIS applications:
With these or other advanced uses of IIS applications, you can perform complicated processing based on the actions users perform in the browser. IIS applications can use Visual Basic code to perform much of the same processing you might have previously done with script, CGI processing, and other methods of Internet application development.
IIS applications are named for Microsoft Internet Information Server, the Web server you use to run your IIS applications. IIS applications can run in any browser, on the Internet or an intranet, and therefore make it easy to reach a broad audience.
This discussion assumes that you are familiar with some basic Internet concepts that are covered in "Introduction to Internet Applications." See it for more information on Internet technologies in general, including HTTP, the Internet development environment, and models of Web browser and Web server interaction.
For More Information See "System Requirements for IIS Applications" for more information on the system configuration needed to develop and test IIS applications.
