Question

I am using this code to set cookie. It is working perfectly in Firefox. but not in IE9.

Below is the code:

HttpCookie visitorCookie = new HttpCookie("VisitorCity", DdlCity.SelectedItem.Text)
{Expires = DateTime.Now.AddMonths(1)};
HttpContext.Current.Request.Cookies.Add(visitorCookie); // Add it to the header

Answer 1

Normally when you want to set a cookie you should add it to the Response, not the Request:

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

It’s the client browser, when sending subsequent the HTTP requests, that will attach the cookie as a request header.
