Request Object
The Request object is an instance of the System.Web.HttpRequest class.
Request object of ASP.NET is related to
retrieving data by the server from the
client.
Tthe Request property of the Page class can be use to access the HttpRequest instance for the current request. For example, Request["key"] can be used for accessing data from the QueryString, Form, Cookies, or ServerVariables collections.
The methods and properties of the HttpRequest class are exposed through the Request properties of the HttpApplication, HttpContext, Page, and UserControl classes.
Note: Unicode support for HttpRequest class members requires IIS version 6.0 or later.
