www.rubyonrails.com bug

The rigth url to get the screecast page is
"http://www.rubyonrails.com/screencasts", but if you try
"http://www.rubyonrails.com/screencasts/" the page looses the
stylesheet and the images beacuse they are in the form of
"css/style.css" rather than "/css/style.css".
This happens everywhere in the site.

Is this a bug? A routing problem?

That acutally happens not only with that, but with docs, community and down...
