(SQL Server) 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 = 1. If the SendCookies property = 1, then any cached cookies are automatically re-sent with subsequent GETs and POSTs.
