Trying to download [this file](http://apps.london.ca/OpenData/ShapeFiles_Zipped/2010_skateboard_parks_shp.zip) from [this website](http://www.london.ca/city-hall/open-data/Pages/Open-Data-Data-Catalogue.aspx) with [`OpenUri`](http://ruby-doc.org/stdlib-2.2.2/libdoc/open-uri/rdoc/OpenURI.html) fails with the runtime error "HTTP redirection loop".
Here is how I can reproduce the error:

~~~
> require 'open-uri'
 => true

> open('http://apps.london.ca/OpenData/ShapeFiles_Zipped/2010_skateboard_parks_shp.zip')
