<script type="text/x-red" data-help-name="stream in">
    <p>Provides an input node for http requests parsed by skipper Middleware, allowing the creation of simple web services.</p>
    <p>The resulting message has the following properties:
        <ul>
            <li>msg.req : <a href="http://expressjs.com/api.html#req">http request</a></li>
            <li>msg.res : <a href="http://expressjs.com/api.html#res">http response</a></li>
        </ul>
    </p>
    <p>For POST/PUT requests, the body is available under <code>msg.req.body</code>. This
       uses the <a href="http://expressjs.com/api.html#bodyParser">Express bodyParser middleware</a> to parse the content to a JSON object.
    </p>
    <p>
       By default, this expects the body of the request to be url encoded:
       <pre>foo=bar&amp;this=that</pre>
    </p>
    <p>
       To send JSON encoded data to the node, the content-type header of the request must be set to
       <code>application/json</code>.
    </p>
    <p>
       <b>Note: </b>This node does not send any response to the http request.
       This should be done with a subsequent HTTP Response node.
    </p>
