Remarks
You can use cookies to store information on the client browser that will be provided in subsequent calls to the site. This can be useful to pass information across pages, or to store small bits of information that might be useful at a later time in the use of the web application
You could use it for example to store a transient user preference ("favorite color", "default action when replying to an email" and so on).
Once constructed, the cookie can be send to the client by calling the HttpResponse.AppendCookie() method. This must be done before any input is sent back to the client.
