Making AJAX as easy as anchor tags

<p>Any content that is returned will be used to replace the content of the current element (or, more commonly, another
  element, via the <code><a href="/attributes/ic-target.html">ic-target</a></code> attribute, see below).  An empty
  response will be interpreted as a No-Op.  See <a href="/responses.html">Intercooler Responses</a> for
  more info.</p>

<p>Since it is common for an action to replace a <em>different</em> element than the one that the action occured
  on, you may want to use the <a href="/attributes/ic-target.html"><code>ic-target</code></a> attribute to target
  a different element for replacement.</p>

<h3>What is the Default Action?</h3>

<p>The default action depends on the type of an HTML element:</p>

<ul>
  <li><code>input</code>, <code>select</code> - A value change.</li>
  <li><code>form</code> - A form submission.</li>
  <li>Everything else - A click.</li>
</ul>

<h3>Using Real HTTP Methods</h3>

<p>By default, intercooler uses <code>POST</code>'s for all non-<code>GET</code> requests, due to older browser
limitations.  It includes the <code>_method</code> parameter and the <code>X-HTTP-Method-Override</code> headers
that indicate the intended HTTP method, but some server-side infrastructure might not understand these conventions.</p>

<p>If you wish to use the actual HTTP method and forgo older browser support, you can use the following meta tag
in your head tag:</p>

<pre>&lt;meta name="intercoolerjs:use-actual-http-method" content="true"/></pre>
