This example not worked when I tried in 1.9.8 and 2.0.0.

Output in 1.9.8:
GET http://updates.html5rocks.com
XHR Error!
status: 0 ()
body:

GET http://www.google.com
XHR Error!
status: 0 ()
body:

Output in 2.0.0:
GET http://updates.html5rocks.com
XHR Loaded
status: 0 ()
body size: 0

GET http://www.google.com
XHR Loaded
status: 0 ()
body size: 0

Is XmlHttpRequest not worked in phantomjs?
