Cookie filter

Overview

Cookie Filter allows you to choose which hosts(websites), the browsers are allowed to send and receive the cookies.

An HTTP cookie (also called web cookie, Internet cookie, browser cookie or simply cookie) is a small piece of data sent from a website and stored in the user's web browser while the user is browsing.

You can control the cookie exchange precisely, between remote websites and users.

You can manage the user privacy (Username & Preferences).

You can also disable the users from logging into their personal accounts.

Example : You can block cookies from advertising websites like tribalfusion.com and doubleclick.net to prevent private information from being transferred to them.

And users able to query the search engines (google, yahoo) but they are not able to login to their personal accounts (Gmail, shopping websites, trading websites).
