How do you track a website using multiple Google Analytics accounts?

Question

Suppose you have two distinct Google Analytic accounts. How are you able to send request data to both accounts on a single page load? For example, on a normal account you'd include code such as:

var _gaq = _gaq || ["UA-12345678-1"];
_gaq.push(['_setAccount', '']);
_gaq.push(['_setDomainName', 'none']);
_gaq.push(['_trackPageview']);

(function() {
  var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
  ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();

Could I simply include another snippet with a different UA ID? Can I pass several UA IDs in one request? Is this even possible to accomplish? Any help would be greatly appreciated!

You can use one GA snippet to send data to two different trackers. Follow the syntax below from the [Asynchronous Tracking Usage Guide][1:

_gaq.push(
  ['_setAccount', 'UA-XXXXX-1'],   //default tracker, unnamed
  ['_trackPageview'],
  ['b._setAccount', 'UA-XXXXX-2'], //second tracker, named 'b'
  ['b._trackPageview']
);

Additional trackers are created by giving them names and prepending the tracker name (along with a dot) in front of the method name. The example above uses the aribrary name 'b'. If a function name is qualified with the name of a tracker, it is executed on that tracker. Otherwise it is executed on the default tracker.
