Answer 1

Here's an alternative to file_get_contents using cURL:

$url = 'http://www.example.com';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$data = curl_exec($curl);
curl_close($curl);

You might want to add this curl_setopt($curl, CURLOPT_ENCODING ,""); if you encounter encoding problem.

Answer 2

1. Open the page using your browser and with the console open, see that the server does indeed send a 401 even when page is sent and viewable

2. On php, open the url in an alternate way to ignore the error (see http://php.net/manual/en/context.http.php)

3. You'll also notice that it's gzip-encoded, see http://php.net/manual/en/function.gzinflate.php

Happy hacking!
