The question is quite straightforward:

How to replace a HttpCookie in MVC3? (Assuming we have access to the HttpContext instance)

the cookie holds an AuthenticationTicket, I need to update some data inside the AuthenticationTicket, and then add it to the cookie again. — Cristian E., Jan 14 '14 at 15:05

var cookie = Request.Cookies["cookieName"];
if (cookie != null)
{
    cookie.Value = "new value";
    Response.SetCookie(cookie);
}

I have a question. When calling `Response.Cookies.Remove("CookieName");` The clients browser still holds this cookie? I saw some examples with Expiration=DateTime.Now.AddDays(-1)... can you explain the effects of both please? – Cristian E. Jan 14 '14 at 15:07
@Christian yes, the server has no control over the client. All `Remove` does is make sure the cookie is not sent back with the request. The only way to make the browser delete the cookie is to expire it. – James Jan 14 '14 at 15:11
I'll do some testings if works, I'll mark it as an answer. Thank you! – Cristian E. Jan 14 '14 at 15:11
I did some tests, and the results are positive :). Hope there are no rocks under the water.. I'll mark it as an answer! Thank you very much for your help! – Cristian E. Jan 14 '14 at 15:23
@Christian you should be fine with this approach, it is the recommended way. – James Jan 14 '14 at 15:23
