Creating an Active Server Page

When a user requests a Web page, the request is submitted as an HTTP request. An ASP application uses the Request Object to interrogate the HTTP request and extract the incoming values. For example, when a user submits a form, the values of the controls on the form are passed in the body of the HTTP request. A Web application can then read these values and use them to return a customized Web page to the user.

This lesson explains how to use the Request object to extract information from a Web page.
