Could use a little help

Been trying to get feedback from my HUE system, heres the code that so far does not work, any help would be appreciated. Code runs once when page is being displayed.

var url = CF.widget("Hue_URL","HUE").label;
var socket = new TCPSocket();
socket.onConnect = function() {
prefix2 = 'GET /api/Y1Vpd5qwJVnjsRIdxFThJR0jsdcdaEvrQVe0NYM/lights'
postfix2 = ' HTTP/1.1\r\n'
try {
socket.write(prefix2+postfix2);
socket.write("HOST:+url+\r\n\r\n");
} catch(e) {
socket.close()
};
};
socket.onData = function() {
var info = socket.read();
