title: Android (Java) file upload to PHP servar fails with Android 4.03
body: <p>We have, with good result, used a script for a game of ours that connects to a php-file in order to upload files to a remote server. When we upgrade to Android 4.03 the script suddenly fails to connect to the server and we have no clue why. It works very well with Android 2.3.4 and older.</p>

  <p>On the server we have the following PHP-file:</p>
  
  <pre><code>&lt;?php
  
  // Where the file is going to be placed 
  $target_path = "orders/";
  
  /* Add the original filename to our target path.  
  Result is "orders/filename.extension" */
  $target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 
  
  if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
  
    echo "The file ".  basename( $_FILES['uploadedfile']['name']).
      " has been uploaded";
      chmod ("orders/".basename( $_FILES['uploadedfile']['name']), 0644);
  
  } 
  else{
  
  echo "There was an error uploading the file, please try again!";
  echo "filename: " .  basename( $_FILES['uploadedfile']['name']);
  echo "target_path: " .$target_path;
  
  }?&gt;

  <p>Any help with this problem is appreciated. Why does it fail with Android 4.03 whan it works flawlessle with previous versions?</p>
  
  <p>Thank you!</p>
