+<h1>XML Transaction &mdash; Retrieving a Yahoo! Weather RSS (XML) Feed via a Server-Side Proxy</h1>
+
+<div class="exampleIntro">
+	<p>This example demonstrates how to use IO and a PHP proxy &mdash; to work around XMLHttpRequest's same-domain policy &mdash; to retrieve an XML document from <code>http://xml.weather.yahoo.com/forecastrss</code>.</p>
+
+<p>To try out the example, fill in your five-digit US zip code, or Location ID.</p>
