I press CTRL-Q to see the documentation of this method:

/// <summary>
/// Some URLs are just a redirect to another URL. Let's skip those.

/// </example>
/// <param name="url"></param>
/// <returns></returns>
private static bool DoesContainAnotherUrl(Uri url)
{
return (url.AbsoluteUri.LastIndexOf("http") != 0);
}

This is the error I get:
"an error occurred while parsing EntityName. Line 6, position 75.
