URLLoader throws Error#2048 on Mac

Question

Hi,
are there any known issues regarding URLLoaders and Macs?
My flash application seems to run correctly on Windows but not on a mac.
It is supposed to retrieve data from a php file with the following code:.
<?php require_once(connect...); ?>
<?php
mysql_select_db($database_conn, $conn);
// OUTPUT TO FLASH
//all name=value pairs are separated by &
$query = "SELECT * FROM news ORDER BY id DESC";
$resultado = mysql_query($query,$conn);
$total = mysql_num_rows($resultado);
$output = "";
if ($resultado) {
  $i=0;
  while ($myrow = mysql_fetch_array($resultado)) {
  $output .= "&data".$i."=".urlencode($myrow['data']).
        "&hora".$i."=".urlencode($myrow['hora']).
        "&noticia".$i."=".urlencode($myrow['noticia']);
  $i++;
} else {
  $error = "Sorry could not access Events Database";
// send the data to Flash using the URL encoded format
echo "total=".urlencode($total)."&error=".urlencode($error).$output;
?>
When loaded directly from a browser, the php code works fine both on Windows and Mac.
But the flash app throws a Error #2048 on Mac.
here's the code for the app:
public class main extends MovieClip
   private var l:URLLoader;
  private var l1:URLLoader;
  private var tx:txField;
  private var tx1:txField;
  public function main():void
  l = new URLLoader
  l.addEventListener(Event.COMPLETE, comp);
  l.addEventListener(SecurityErrorEvent.SECURITY_ERROR, err);
  l.addEventListener(IOErrorEvent.IO_ERROR, IOErr)
  l.load(new URLRequest("http://.../myPhp.php"));
  l1 = new URLLoader
  l1.addEventListener(Event.COMPLETE, comp1);
  l1.load(new URLRequest("http://mariofranco.net/resources/home.txt"));
  tx = new txField("", 200);
  tx.move(500, 50)
  addChild(tx);
  tx1 = new txField("", 200);
  tx1.move(200, 50)
  addChild(tx1);
  private function err(e:SecurityErrorEvent):void
  tx.text = "erro seguranca: " +e.text;
  private function IOErr(e:IOErrorEvent):void
  tx.text = "erro IO: "+ e.text;
  private function comp(e:Event):void
  trace (l.data);
      tx.text = l.data;
  private function comp1(e:Event):void
  tx1.text = l1.data;
Thank you in advance for any help.

Got it.
The URLRequest works if I remove http://domainName/ and leave only the "myPhp.php file" reference there.
this works (both on Mac and Windows):
l1.load(new URLRequest("resources/myPhp.php"));
this doesn't work on Mac:
l1.load(new URLRequest(http://myDomain/resources/myPhp.php));
