/*
 * Description of the test:
 * 1) We load an image from http://mochi.test which sets a same site cookie
 * 2) We open a new window to
 *    * a same origin location
 *    * a cross origin location
 * 3) We observe that the same site cookie is sent in the same origin case,
 *    but not in the cross origin case, unless the policy = 'lax', which should
 *    send the cookie in a top-level navigation case.
 *
 * In detail:
 * We perform an XHR request to the *.sjs file which is processed async on
 * the server and waits till the image request has been processed by the server.
 * Once the image requets was processed, the server responds to the initial
 * XHR request with the expecuted result (the cookie value).
