/*
 *  You're clearly welcome to edit what comes later, but you shouldn't need to.
 *
 *  A few notes:
 *      - The script uses a sleep(5) before submitting the job and checking the first
 *      time, and then before every subsequent check. This is a long time in computing
 *      worlds, but remember that the server has to do a lot of work. Dropping this to
 *      zero is a great way to get throttled.
 *      - http_build_query() wories about escaping for us
 *      - Designed to integrate with Nagios it uses return codes 0, 2, and 3. Which
 *      represent Success, Failure, and Unknown respectively. This simple implementaiton
 *      doesn't present warn.
 *      - When the check fails it immediately requests a second check against that URL,
 *      including Traceroute, Ping, and DNS lookups. While the results of these lookups
 *      aren't available in the echo'd result, the link to them is. This should help
 *      diagnose problems.
