Приветствую.

Есть проблема отправки get запроса.  

Вот скетч.

Запрос такой GET /rfid_read.php?allow=1&id=550b960911d HTTP/1.1

Когда делаю посылаю запрос через Браузер то получаю правильный ответ. т.е. в базу заносится данные

"GET /rfid_read.php?allow=1&id=550b960911d HTTP/1.1" 200 1 "-"

А через Arduino получаю вот так "GET /rfid_read.php?allow=1&id=550b960911d HTTP/1.1" 400 950 "

В чем ошибка? помогите пожалуйста
