Caching cookies in-memory.

See more HTTP Examples

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. SQL Server
