C # HttpListener Cookies expiring after a session, even if an expiration time is set

Question

I have a class HttpListenerfor handling logins on a page and can successfully set a cookie, but the cookie expires at the end of the session (using the cookie extension in Chrome, shows that cookie is a session cookie). Here is the code snippet:

CookieCollection ccol = new CookieCollection();    
Cookie loginCookie = new Cookie();

loginCookie.Name = "login";
loginCookie.Value = "loggedin";
loginCookie.Expires = DateTime.Now.AddMinutes(60);
ccol.Add(loginCookie);
context.Response.Cookies = ccol;

As long as I am in the same session, I can access the cookie without any problems.
