(Delphi DLL) Caching cookies in-memory.

Caching cookies in-memory. To automatically save cookies to an in-memory cache, set the CookieDir property equal to the keyword "memory". Also, set the SaveCookies property = True. If the SendCookies property = True, then any cached cookies are automatically re-sent with subsequent GETs and POSTs.
