<p>
  With <a href="http://benalman.com/projects/php-simple-proxy/">Simple PHP Proxy</a>, your JavaScript can
  access content in remote webpages, without cross-domain security limitations, even if it's not available
  in JSONP format. Of course, you'll need to install this PHP script on your server.. but that's a small
  price to have to pay for this much awesomeness.
</p>
<p>
  Please note that while jQuery is used here, you can use any library you'd like.. or just code your
  XMLHttpRequest objects by hand, it doesn't matter. This proxy just acts a bridge between the client
  and server to facilitate cross-domain communication, so the client-side JavaScript is entirely left
  up to you (but I recommend jQuery's <a href="http://docs.jquery.com/Ajax/jQuery.getJSON">getJSON</a>
  method because of its simplicity).
</p>
<p>
  Please see the <a href="http://benalman.com/projects/php-simple-proxy/">project page</a> and 
  <a href="http://benalman.com/code/projects/php-simple-proxy/docs/">documentation</a> for more usage
  information.
