google analytics - multiple trackers on one page (cookie conflict)

Now made easy with the new asynchronous tracking code. :)

https://developers.google.com/analytics/devguides/collection/gajs/#MultipleCommands

You can install multiple instances of the Google Analytics tracking code on your web pages to send data to multiple properties in your account.https://support.google.com/analytics/answer/1032400?hl=en

Or you can get creative and do the following per Google's instructions. https://developers.google.com/analytics/devguides/collection/analyticsjs/advanced#multipletrackers

<script>  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');  ga('create', 'UA-XXXX-Y', 'auto');  ga('create', 'UA-XXXX-Y', 'auto', {'name': 'newTracker'});  ga('send', 'pageview');  ga('newTracker.send', 'pageview');</script>

Don't have to use different cookie names as Google Analytics happily works with multiple trackers on the same page. See answers for question Google Analytics - Multiple Trackers for Several Accounts?.

Update

It turns out that using multiple trackers is a working method but has some pitfalls. One of those, that is, you cannot apply different user segmentation for each of them. John Henson demonstrates a workaround that coerces GA to use different cookies, may be you should check it.
