This property determines whether automatic cookies are disabled.
If it is true, PageLoadMethod must
be effectively MonikerForHtml.
The HTML engine manages cookies as it receives HTTP/HTTPS
responses and sends HTTP/HTTPS requests. If this property is set to
true, cookies stored in the local cookie database will not be sent
in requests, and cookies received in responses will not be stored
in the local cookie database.
Cookies specified in HttpAdditionalHeaders are not sent
in requests if automatic cookies are enabled. Set this property to
true if cookies are specified in HttpAdditionalHeaders.
