Dan,

Thanks. Here is the error I get when executing the above code:

Timeout::Error (execution expired):
c:/ruby/lib/ruby/1.8/timeout.rb:54:in `open'
c:/ruby/lib/ruby/1.8/timeout.rb:56:in `timeout'

I know it's a valid URL. The page I am trying to access is sitting on
the same box as my rails app.
