The Privacy tab provides the following options for user privacy protection:
Filtering of both persistent and session cookies from third-party servers (Third party cookies).
These cookies are downloaded from servers independent from the page itself (i.e. ad cookies).
This option can be used to filter persistent cookies.
These cookies contain information which can be sent to a particular Web server whenever the page is visited again by the user — the server is informed that the user has already visited the page, this user's preferences and other information.
This option filters temporary cookies (the cookies are saved during one session only —until the Web browser is closed). These cookies are used only if the user opens a particular page (or a particular server or a server in a particular domain) again within the same session — that are removed when the all windows of the browser are closed.
Note: Even if filtering of all types of cookies is enabled, a cookie may be saved under certain circumstances. This situation arrives, for example, when a cookie is saved by a script on a Web page — this is not a type of network traffic and therefore Kerio Personal Firewall does not detect such actions. However, filtering of cookies does not allow to send any cookie to the server, so that saved cookies are unusable. This implies that the firewll protects user's privacy even in these cases.
