XMLHttpRequest.open, does it work on remote websites?
<p>I'm a bit confused about this. </p>

<p>Does XMLHttpRequest work on a remote URL or does it have to be a local file? There seems to be mixed information on the net.</p>

<p>According to w3.org: <em>The XMLHttpRequest  object can be used by scripts to programmatically connect to their originating server via HTTP.</em> </p>

<p>But I've seen it used to access non-local web pages (in vista gadgets for instance for rss feeds) without using a proxy...</p>

<p>Enlighten me please!</p>
