Cookie code

Toomoro on Post....

Cookies in Asp.net

A Cookie is a small text file that the browser creates and stores on the hard drive of your machine. Cookie is just one or more pieces of information stored as text strings. A Web server sends you a cookie and the browser stores it. The browser then returns the cookie to the server the next time the page is referenced. The most common use of a cookie is to store information about the user and preferences the user makes. For example, assume you like DVD's and register with Ebay to participate in online auctions.
