Description:
------------
file_get_contents fails to open a stream with an "http://localhost inside". 
Pinging or open the url via a browser works fine.
The same environment (apache, php.ini, etc.) works on XP.
Any ohter url not containing localhost(includung 127.0.0.1) works fine.



Reproduce code:
---------------
<?php
$myUrl = "http://localhost/index.html";
//$myUrl = "http://127.0.0.1/index.html";
if (!($cont=file_get_contents($myUrl))) {
  echo "<br/>error opening Url:" . $myUrl . " <br/>";
 }
 else {
   echo "$cont";
 }
?>
