JSONLINT: Parse error on string

Question

I'm trying to verify the following JSON on www.jsonlint.com: http://s2g.supsi.ch/hcd/test.json

If I copy and paste the text in jsonlint the JSON is verified. However if I enter the JSON URL ( http://s2g.supsi.ch/hcd/test.json ) to jsonlint I receive the following error:

Parse error on line 1:
^
Expecting '{', '['

I don't understand why it doesn't work. Could be the text encoding?

Here is the code which reads the URL:

    if (jsonVal.substring(0, 4).toLowerCase() === "http") 
      {
      $.post("proxy.php", {"url": jsonVal}, function (responseObj) 
        {
        $('#json_input').val(responseObj.content);
        validate();
        }, 'json');

Here is the issue:

• The response from the http://jsonlint.com/proxy.php server URL returns a bad status code rather than the content in question.
