 /*
 * This is a NodeJS script that crudely simulates a captive portal.  It is
 * intended for use by QA and engineering while working on the captive portal
 * feature in Firefox.
 *
 * It maintains the authentication state (logged in or logged out). The root
 * URL ("/") displays either a link to log out (if the state is logged in) or
 * to log in (if the state is logged out).  A canonical URL ("/test") is
 * provided: when this URL is requested, if the state is logged in, a "success"
 * response is sent. If the state is logged out, a redirect is sent (back to
 * "/"). This script can be used to test Firefox's captive portal detection
 * features by setting the captivedetect.canonicalURL pref in about:config to
 * http://localhost:8080/test.
 *
 * Originally written by Nihanth.
 *
 * Run it like this:
 *
 *  mach node browser/base/content/test/captivePortal/captive-portal-simulator.js
