I don't know what you're trying to do with this task, and I know it doesn't help you solve the problem you're having ...

... but are you aware that there's a robots.txt on the site, specifically requesting that you not automate access to its contents?

(yes, I know, there are many differing interpretations of what types of programs should use the robots.txt -- for instance, if you manually started the process, but it just grabbed the pages to present them as one page for you, that's likely different than trying to retrieve the pages for pre-caching or a search engine spider)

Update: ikegami is right -- my browser put its insertion bar at the end, which I mistook for a /. (bah ... time to get my eyes checked again). They specifically allow robot access. Feel free to down vote my oversight.
