/**
 * This script collects information on visitors, based
 * on their client session. It finds out which page they
 * were on when they go there, and by virtue of sending
 * that information to the logger, their IP. This is
 * information that you're sending already, anyway, but
 * I want you to know that this is what's going on.
 *
 * Which is why this script is not obfuscated. It simply
 * grabs your document.referrer value, which (unless Do
 * Not Track is enabled) will contain the location of
 * the page you were on before you clicked a link to this
 * page, and GETs that to my logger.
 *
 * If you want to know what gets logged, have a look
 * at the ./src/logger/logger.php file on github.
 *
 * If that's too much effort:
 * - the request URL
 * - the referrer URL (if there is one)
 * - the user agent
 *
