Users can define and import a custom privacy preference file that controls how both first-party and third-party cookies should be treated. For more information, see http://msdn.microsoft.com/en-us/library/ms537344(VS.85).aspx.
Users can specify any of the following operations for a cookie from a site (either first-party cookies or third-party cookies; with or without a compact P3P policy):
Prompt: Prompts the user for consent.
forceFirstParty: Leash cookies so that they are sent only in a first-party context.
forceSession: Convert persistent cookies to session cookies.
The custom privacy file also allows users to define separate behaviors for first-party cookies and third-party cookies.
The custom privacy file supports rules (with actions) for each token on the compact P3P header. The action can be one of the operations in the previous list.
<firstParty noPolicyDefault="accept" noRuleDefault="forceSession" alwaysAllowSession="no">
<if expr="DSP" action="prompt"></if>
