class HTTPResponse(ElementBase):

    """
    When the HTTP Server responds, it does so by sending an `iq` stanza
    response (type=`result`) back to the client containing the `resp` element.
    Since response are asynchronous, and since multiple requests may be active
    at the same time, responses may be returned in a different order than the
    in which the original requests were made.

    Examples:
    ::

        <iq type='result'
            from='httpserver@clayster.com'
            to='httpclient@clayster.com/browser' id='2'>
            <resp xmlns='urn:xmpp:http'
                  version='1.1'
                  statusCode='200'
                  statusMessage='OK'>
                <headers xmlns='http://jabber.org/protocol/shim'>
                    <header name='Date'>Fri, 03 May 2013 16:39:54GMT-4</header>
                    <header name='Server'>Clayster</header>
