Using Google Analytics and Urchin at the same time?

You can use Google Analytics and Urchin together easily but be aware of these pitfalls:

Although the Google Analytics instructions refer to using Google Analytics with Urchin using the pageTracker._setLocalRemoteServerMode();. The Google Analytics instructions omit the fact you need ._utm.gif which is included in the Urchin instructions. The legacy Google Analytics coding instructions also omit this fact.

Also, although in the majority of cases pageTracker._setLocalRemoteServerMode(); will work, when it comes to tracking across multiple domains we have seen this fail. We've had to result to using the older urchin.js for Google Analytics and _userv=2.

Our understanding is that "officially" Google Analytics ga.js in incompatible with Urchin and so the urchin.js should be used.
