Demo on activescaffold.com throws the browser into a redirect loop

What steps will reproduce the problem?
1. Go to activescaffold.com
2. Click either the 'Demo' tab or the 'View Demo' image link
3. Watch your browser dive into an infinite redirect loop and eventually, 
given it does not suck really bad, notify you about it

What is the expected output? What do you see instead?
Expected output: the activescaffold demo page and a whoa reaction.
See instead: "Waiting for demo.activescaffold.com... Connecting... Waiting 
for demo.activescaffold.com... Connecting... Waiting for 
demo.activescaffold.com... Connecting... This webpage has a redirect 
loop."

What version (or revision) of the product are you using?
Tested in:
Chrome 5.0.307.11 beta
Firefox 3.6
on Mac OS 10.6.2 Snow Leopard
