<p>Creates an HTTP end-point for creating web services.</p>
<h3>Outputs</h3>

<dd>For a GET request, contains an object of any query string parameters.
Otherwise, contains the body of the HTTP request.</dd>
<dt>req<span class="property-type">object</span></dt>
<dd>An HTTP request object. This object contains multiple properties that
provide information about the request.
<ul>
<li><code>body</code> - the body of the incoming request. The format
will depend on the request.</li>
<li><code>headers</code> - an object containing the HTTP request headers.</li>
<li><code>query</code> - an object containing any query string parameters.</li>
<li><code>params</code> - an object containing any route parameters.</li>
<li><code>cookies</code> - an object containing the cookies for the request.</li>
<li><code>files</code> - if enabled within the node, an object containing
any files uploaded as part of a POST request.</li>
</ul>
</dd>
<dt>res<span class="property-type">object</span></dt>
<dd>An HTTP response object. This property should not be used directly;
the <code>HTTP Response</code> node documents how to respond to a request.
This property must remain attached to the message passed to the response node.</dd>
</dl>
<h3>Details</h3>
<p>The node will listen on the configured path for requests of a particular type.
The path can be fully specified, such as <code>/user</code>, or include
named parameters that accept any value, such as <code>/user/:name</code>.
When named parameters are used, their actual value in a request can be accessed under `msg.req.params`.</p>
<p>For requests that include a body, such as a POST or PUT, the contents of
the request is made available as <code>msg.payload</code>.</p>
<p>If the content type of the request can be determined, the body will be parsed to
any appropriate type. For example, <code>application/json</code> will be parsed to
its JavaScript object representation.</p>
<p><b>Note:</b> this node does not send any response to the request. The flow
must include an HTTP Response node to complete the request.</p>

<p>Sends responses back to requests received from an HTTP Input node.</p>
<h3>Inputs</h3>
<dl class="message-properties">
<dt>payload <span class="property-type">string</span></dt>
<dd>The body of the response.</dd>
<dt class="optional">statusCode <span class="property-type">number</span></dt>
<dd>If set, this is used as the response status code. Default: 200.</dd>
<dt class="optional">headers <span class="property-type">object</span></dt>
<dd>If set, provides HTTP headers to include in the response.</dd>
<dt class="optional">cookies <span class="property-type">object</span></dt>
<dd>If set, can be used to set or delete cookies.</dd>
</dl>
<h3>Details</h3>
<p>The <code>statusCode</code> and <code>headers</code> can also be set within
the node itself. If a property is set within the node, it cannot be overridden
by the corresponding message property.</p>
<h4>Cookie handling</h4>
<p>The <code>cookies</code> property must be an object of name/value pairs.
The value can be either a string to set the value of the cookie with default
options, or it can be an object of options.<p>
<p>The following example sets two cookies - one called <code>name</code> with
a value of <code>nick</code>, the other called <code>session</code> with a
value of <code>1234</code> and an expiry set to 15 minutes.</p>
<pre>
msg.cookies = {
name: 'nick',
session: {
value: '1234',
maxAge: 900000
}
}</pre>
<p>The valid options include:</p>
<ul>
<li><code>domain</code> - (String) domain name for the cookie</li>
<li><code>expires</code> - (Date) expiry date in GMT. If not specified or set to 0, creates a session cookie</li>
<li><code>maxAge</code> - (String) expiry date as relative to the current time in milliseconds</li>
<li><code>path</code> - (String) path for the cookie. Defaults to /</li>
<li><code>value</code> - (String) the value to use for the cookie</li>
</ul>
<p>To delete a cookie, set its <code>value</code> to <code>null</code>.</p>
