CookieContainer.Add Method (Uri, Cookie)
Assembly: System (in System.dll)
If your URI corresponds to your local domain and sends to all the hosts on the local domain, set the Cookie Domain property equal to ".local". Otherwise, make sure it matches the host name used in the URI.
If the Count property equals the Capacity property, one or more Cookie instances are removed from the container before adding the cookie parameter. Enough Cookie instances are removed to bring Count below Capacity as follows: if there are expired instances in scope, they are cleaned up. If not, then the least recently used CookieCollection is found and removed from the container.
