We created Milk to illustrate the concept of functional privacy. Milk is designed to limit cross-site tracking without reducing functionality for the user. The general idea is to restrict, or bind, cookies to the first-party site from which they were created rather than disabling cookies entirely.
Send questions and comments to email@example.com.
Milk implements cookie binding by intercepting cookies both before they are stored and before they are sent. Imagine this simplified example using a single first-party site. When the user visits example.com, the server responds with an HTTP Set-Cookie header instructing the browser to store a cookie. Milk will rewrite the cookie before it is stored, appending the key "example.com!!!" to the cookie’s name. For subsequent web requests to example.com, Milk will rewrite the HTTP Cookie header to both remove the domain-specific keys and ensure that only cookies with the appropriate key are sent back to the server.
