Matweb.com: How to get the page source?

Question

I have a url:
http://www.matweb.com/search/DataSheet.aspx?MatGUID=849e2916ab1541be9ff6a17b78f95c82

I want to download the source code from this page using this code:

private static string urlTemplate = @"http://www.matweb.com/search/DataSheet.aspx?MatGUID=";

static string GetSource(string guid)
{
    try
    {
        Uri url = new Uri(urlTemplate + guid);

        HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
        webRequest.Method = "GET";               

        HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();

        Stream responseStream = webResponse.GetResponseStream();
        StreamReader responseStreamReader = new StreamReader(responseStream);
        String result = responseStreamReader.ReadToEnd();

        return result;
    }
    catch (Exception ex)
    {
        return null;
    }
}

When I do this, I get:

You do not seem to have cookies. MatWeb Requires cookies to be enabled.

Ok, I understand, so I added the lines:

CookieContainer cc = new CookieContainer();  
webRequest.CookieContainer = cc; 

I got:

Your IP address has been limited due to overuse. The problem can be exacerbated when the IP address can be used by many people in the company or through an Internet service provider. We apologize for any inconvenience.
