I am sure that you leave cookies into client computer on purpose or without knowing if you're an asp.net developer. Also if you create a sales website, there must be steps on this sales applicatiion and you should get the data from a previous page to another pages. The best way is always cookie if the information is not so sensetive.
But what if we wanna delete them ? It is not as simple as creating them (essentially it is but not by directly deleting it) We cannot directly delete a file from user's computer. So what will we do?
I assume there are another ways but the one way is setting the expiry date on a previous date. Here is the example;
if (Request.Cookies["UserSettings"] != null) {
HttpCookie myCookie = new HttpCookie("UserSettings");
//Here, we are setting the time to a previous time.
//When the browser detect it next time, it will be deleted automatically.
myCookie.Expires = DateTime.Now.AddDays(-1d);
Response.Cookies.Add(myCookie);
}
Hope this helps :)
