Прошу объяснить и помочь решить мне вопрос, возникающий при установке сервера dklab_realplexor. Введение: стояла задача поставить версию realplexor c++ на vds. Сам realplexor стоит на realplexor.shyass.space, а данные ловятся на shyass.space соответственно. При запросе в консоли wget
realplexor.shyass.space все хорошо.
Но при попытке отправить и принять данные
<?
require_once "Realplexor.php";
$rpl = new Dklab_Realplexor(
"127.0.0.1",
"10010",
"nsp"
$rpl->send("Alpha", 'hello');
?>
var realplexor = new Dklab_Realplexor(
"http://realplexor.shyass.space/",
"nsp"
);
realplexor.subscribe("Alpha", function(data, id) {
document.getElementById('first').innerHTML += data + "<br>";
});
realplexor.execute();
возникает вот такая ошибка: Permission denied to access property "Dklab_Realplexor_Loader".
Пытался разобраться - понял, что дело в различных хостах, но так и не решил этот вопрос. Прошу помочь. Заранее всем спасибо.
P.S.
