    All HTTP communication is done using the `Request`/`Response` paradigm.
    Each HTTP Request is made sending an `iq` stanza containing a `req` element
    to the server. Each `iq` stanza sent is of type `set`.

    Examples:
    <iq type='set' from='a@b.com/browser' to='x@y.com' id='1'>
        <req xmlns='urn:xmpp:http' method='GET' resource='/api/user' version='1.1'>
            <headers xmlns='http://jabber.org/protocol/shim'>
                <header name='Host'>b.com</header>
            </headers>
        </req>
    </iq>

    <iq type='set' from='a@b.com/browser' to='x@y.com' id='2'>
        <req xmlns='urn:xmpp:http' method='PUT' resource='/api/users' version='1.1'>
            <headers xmlns='http://jabber.org/protocol/shim'>
                <header name='Host'>b.com</header>
