This method will return reference to all attributes for
the cookie. For example, you may receive something like
this from the server (in response headers):
in which case there are 2 cookies: one with name
'BrowserTest' and another with name
'PRresult'. Since attributes are separated with
semicolon, this means that first cookie has 4
attributes: domain, path, HTTPOnly and version. When
cookie is to be returned in next request, you don't
need to send cookie attributes, but perhaps you might want
to check them if they apply for next request.
For example, if there is 'Expires' attribute,
then perhaps you don't need to send cookie - because
date provided in the cookie already expired?
Or, if there's 'Path' attribute, and you
don't request same location - you don't need to
send the cookie.
Attributes are kept in HttpHeaders object -
since this object is good enough to hold
'name/value' pairs, even it's primary purpose
is to store headers (as the name says).
