If you try to do an ajax request on a different domain. You’ll get nothing. Looking a bit deeper into the request I noticed that the status code isn’t 200 or 403 nor 404 like expected. Nope it is 0. (jquery ajax statusCode 0). This means the browser doesn’t allow a crossdomain request. The easiest way for me to solve this was to create a proxy php script. Now I can send my ajax request to a url on my server while the PHP script does the real request to the other server.

This is the php script

/**
* GetFromHost()
*
* @param string $host
* @param int $port
* @param string $path
* @param string $referer
* @param bool $keepalive
* @return
*/
function GetFromHost($host, $port, $path, $referer,$keepalive=false) {

 $fsocket = fsockopen($host, 80, $errno, $errstr, 30);

 if($fsocket){
 $request =     "GET $path HTTP/1.1\r\n";
 $request .= "Host: $host\r\n";
 $request .= "Referer: $referer\r\n";
 $request .= 'User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) ';
 $request .= "Gecko/20021204\r\n";
 $request .= 'Accept: text/xml,application/xml,application/xhtml+xml,';
 $request .= 'text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,';
 $request .= "image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1\r\n";
 $request .= "Accept-Language: en-us, en;q=0.50\r\n";
 //$request .= "Accept-Encoding: gzip, deflate, compress;q=0.9\r\n";
 $request .= "Accept-Charset: ISO-8859-1, utf-8;q=0.66, *;q=0.66\r\n";
 if($keepalive==true){
 $request .= "Keep-Alive: 300\r\n";
 $request .= "Connection: keep-alive\r\n";
 }
 else
 {
 $request .= "Connection: close\r\n";
 }
 //$request .= "Content-Type: application/x-www-form-urlencoded\r\n";
 //$request .= "Content-length: ". strlen($data_to_send) ."\r\n";
 $request .= "\r\n";
 //$request .= $data_to_send;

 fputs($fsocket, $request);

 $res ='';
 while(!feof($fsocket)) {
 $res .= fgets($fsocket, 1024);
 }
 fclose($fsocket);

 return $res;

 }
 else
 {
 return false;
 //echo "Fehlgeschlagen: ".$fsocket . $host .':'. $port;
 }

}

$x = GetFromHost("www.example", "80", "/deep/url/kinda/", "");
$x = explode('Content-Type: text/html',$x);
$output = preg_replace('/\s+(\r\n|\r|\n)/', '$1', $x['1']);//remove white space and tabs at the line ends
echo $output;

maybe you have to edit the explode part for server to separate the header fom the real content.
