<?php
// Tests remoteControlUrl() in web/includes/control_functions.php: in a
// multi-server setup a PTZ or other control request for a monitor that another
// server records is handed to that server, which runs its zmcontrol.pl.
//
// Before, the server that got the request sent the zmcontrol option string to
// the other server's monitors/daemonControl API, which only starts and stops
// zmcontrol.pl, so the camera never moved and the request answered "Failed".
//
// Run: php tests/php/test_remote_control_url.php
