/**
* Provides **policy** and **persistence** for HTTP cookies.
*
* As policy, implementations of this interface are responsible for selecting which cookies to
* accept and which to reject. A reasonable policy is to reject all cookies, though that may
* interfere with session-based authentication schemes that require cookies.
*
* As persistence, implementations of this interface must also provide storage of cookies. Simple
* implementations may store cookies in memory; sophisticated ones may use the file system or
* database to hold accepted cookies. The [cookie storage model][rfc_6265_53] specifies policies for
* updating and expiring cookies.
*
* [rfc_6265_53]: https://tools.ietf.org/html/rfc6265#section-5.3
