HttpWebRequest.GetResponseStream returns an empty string

I have been trying every way possible to download get the response stream from a page using HttpWebRequest, which works fine on everything else but no this page. As you see the data returned is an HTML but it have a some meta tag which I am not expert in, but what ever i try to get this block

{"error":4,"message":"Unsupported link format or unsupported hoster"}

It seems that I can't, I tried to specify the GET content-type as "text/json" but nothing helped.

Below is the HTML content returned when I open the page on the browser, but in code it returns empty string.

    <html>
    <meta style="visibility: hidden !important; display: block !important; width: 0px !important; height: 0px !important; border-style: none !important;"></meta>
    <head></head>
    <body>
      <pre style="word-wrap: break-word; white-space: pre-wrap;">{"error":4,"message":"Unsupported link format or unsupported hoster"}
      </pre>
    </body>
    </html>

Edit:

I have tried copy the same html above in a page on localhost and tried to fetch it's content and it actually worked, could there maybe some restriction in the IIS that could prevent fetching content ?

I had the same problem and the cause was that I previously had set the method to HEAD and in later revisions had the need to parse the body.

Do you have evidence that the problem is with the client? The more appropriate question is: Why is the server sending this strange content? The client just receives whatever the server sends.

I suggest you debug the server to find out, or ask a new question containing your server-side code and asking specifically about it.

Try to use the WebRequest class. Here you find the documentation for it.

You have this example in the page:

// Create a request for the URL.        
WebRequest request = WebRequest.Create ("[your_url]");
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
// Display the status.
Console.WriteLine (response.StatusDescription);
// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content. 
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Cleanup the streams and the response.
reader.Close ();
dataStream.Close ();
response.Close ();

This will print in Console the HTML content of that page.
