                                       throws JSONException
        Convert an HTTP header string into a JSONObject. It can be a request header or a response header. A request header will contain
        {
            Method: "POST" (for example),
            "Request-URI": "/" (for example),
            "HTTP-Version": "HTTP/1.1" (for example)
         }
        A response header will contain
        {
            "HTTP-Version": "HTTP/1.1" (for example),
            "Status-Code": "200" (for example),
            "Reason-Phrase": "OK" (for example)
         }
        In addition, the other parameters in the header will be captured, using the HTTP field names as JSON names, so that
            Date: Sun, 26 May 2002 18:06:04 GMT
            Cookie: Q=q2=PPEAsg--; B=677gi6ouf29bn&b=2&f=s
            Cache-Control: no-cache
        become
        {...
            Date: "Sun, 26 May 2002 18:06:04 GMT",
            Cookie: "Q=q2=PPEAsg--; B=677gi6ouf29bn&b=2&f=s",
            "Cache-Control": "no-cache",
         ...}
        It does no further checking or conversion. It does not parse dates. It does not do '%' transforms on URLs.
        Parameters:
        string - An HTTP header string.
        Returns:
        A JSONObject containing the elements and attributes of the XML string.
