/*
 * Description of the test:
 *   We show that we can separate the safebrowsing cookie by creating a custom
 *   LoadContext using a reserved AppId (UINT_32_MAX - 1). Setting this
 *   custom LoadContext as a callback on the channel allows us to query the
 *   AppId and therefore separate the safebrowing cookie in its own cookie-jar.
 *   For testing safebrowsing update and rekey we do >> NOT << emulate a response
 *   in the body, rather we only set the cookies in the header of the response
 *   and confirm that cookies are separated in their own cookie-jar.
 *
 * 1) We init safebrowsing and simulate an update (cookies are set for localhost)
 *
 * 2) We simulate a rekey request (cookies should be set for localhost)
 *
 * 3) We open a channel that should send regular cookies, but not the
 *    safebrowsing cookie.
 *
 * 4) We open a channel with a custom callback, simulating a safebrowsing cookie
 *    that should send this simulated safebrowsing cookie as well as the
 *    real safebrowsing cookies. (Confirming that the safebrowsing cookies
 *    actually get stored in the correct jar).
