Do relative URL's ( for ajax requests ) need a preceding `/`
<p>I noticed it works both ways, but which way are you suppose to do it?</p>

<p><strong>Particular Case</strong></p>

<pre><code>$FOO.ajax({
    type:       'get',
    url:        src, // the src works with both a preceding / and with out
    // ...
</code></pre>
