HTTP REQUEST RESPONSE OBJECT - WEB APPLICATION USING C# LAB
The document contains code for several ASP.NET web pages that demonstrate using request and response objects to work with query strings, browser details, and cookies. The home page links to pages for querying query strings, accessing browser details, and setting/reading cookies. The query string and browser pages display values from the respective request objects. The cookies page uses cookies to set the background color for 10 seconds when a color is selected from a dropdown.
