<p>This will test the URL canonicalization by assigning a host with an empty port specifier to window.location.host</p>
<p>Clicking the following button should change the host in the current URL to "www.example.com:".  It actually loading is not important - 
if you see "www.example.com:0" the test has failed.  You should see "www.example.com:"</p>
