code: public HttpInputStream get(URL url, boolean failIfNotOK) throws IOException {
          return get(url, failIfNotOK, FOLLOW_REDIRECTS);
      }
docs: Get an HTTP resource with the response as an InputStream, given a URL.
  This method will follow redirects if FOLLOW_REDIRECTS is true. Note that
  if the HTTP response has no body, the InputStream will be empty. The
  success of a request can be checked with getResponseCode(). Usually
  you'll want to see a 200. See
  http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html for other codes.
  
  @param url
  A URL that we want to do an HTTP GET upon
  @param failIfNotOK
  boolean value indicating if an exception should be thrown if we do
  NOT receive an HTTP 200 response (OK)
  @return HttpInputStream the HTTP response
  @throws IOException
