redirect

I ultimately want to get data from this page:

http://www.canadapost.ca/cpotools/apps/track/personal/findByTrackNumber?trackingNumber=0656887000494793

But that page forwards to:

http://www.canadapost.ca/cpotools/apps/track/personal/findByTrackNumber?execution=eXs1

So when I use open (open-uri) to try and fetch the data, it throws a RuntimeError error saying HTTP redirection loop:

So I'm not really sure how to get that data after it redirects and throws that error.
