uppdatera expire tiden på befintlig cookie i .net c#?

Hej,

Har lite problem med att uppdatera tiden på befintlig cookie.

Flöde:

Kod:

//Sätter cookie första gången

HttpCookie myCookie = new HttpCookie("CUser");

myCookie["userId"] = sHashedUserId;

myCookie.Expires = DateTime.Now.AddDays(1d);

HttpContext.Current.Response.Cookies.Add(myCookie);

Kod:

//Uppdatera befintliga cookien

if (cookietiden <= HttpContext.Current.Request.Cookies["CTPUser"].expire)

{

HttpCookie myCookie = HttpContext.Current.Request.Cookies["CTPUser"];

myCookie.Expires = DateTime.Now.AddDays(1d);

HttpContext.Current.Response.Cookies.Add(myCookie);

}

denna kod verkar inte fungera.... dvs den sätter inte om befintliga cookien.

tacksam för svar.

Citat:

You cannot directly modify a cookie. Instead, changing a cookie consists of creating a new cookie with new values and then sending the cookie to the browser to overwrite the old version on the client. The following code example shows how you can change the value of a cookie that stores a count of the user's visits to the site:

Kod:

int counter;

if (Request.Cookies["counter"] == null)

    counter = 0;

else

{

    counter = int.Parse(Request.Cookies["counter"].Value);

}

counter++;



Response.Cookies["counter"].Value = counter.ToString();

Response.Cookies["counter"].Expires = DateTime.Now.AddDays(1);
