When we leave "Treat www and non-www versions of the domain as the same site" in the Misc. Project Settings unchecked, we would NOT expect to see any results with www in the URL -- but we are. In fact, the results are identical to when we have that box checked.

To further test this, we created two separate projects, both with the box unchecked, using the www and the non-www URL as each project's primary URL receptively. Again, the results were identical.

Why does this feature not work as expected?

Thanks,
Michael

Would you mind sending us both projects via Help -> Send project to support? We will take a look and see what exactly is wrong.
