Problem with jquery setting wrong RequestUrl
<p>I'm using the $ajax interface, working from localhost.</p>

<p>First example works as expected, RequestUrl (seen e.g. in Chrome Developer tools network tab) is: /commentSubmitted</p>

<pre><code>$.ajax({
        type: "POST",
        url: '/commentSubmitted',
        data: "hi"});
</code></pre>

<p>This here doesn't work as expected, it appends the current browser url (referrer) to it:</p>

<pre><code>$.ajax({
        type: "POST",
        url: 'anyotherstring/commentSubmitted',
        data: "hi"});
</code></pre>

<p>I would like to have the RequestUrl always be the exact string I specify. For some reason the RequestUrl looks like this: <code>/nested/url/I/dont/care/about/anyotherstring/commentSubmitted</code></p>
