If you add a Cookie instance for just one specific host, do not set the Domain property of the Cookie instance. This is set automatically, based on the URI.
If your URI corresponds to your local domain and sends to all the hosts on the local domain, set the CookieDomain property equal to ".local". Otherwise, make sure it matches the host name used in the URI.
If the Version property of a Cookie is Netscape, the Path property of the Cookie, if not set explicitly, is derived from the URI and is the complete path from the URI, including the page name.
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.
