Allows you to resolve redirecting urls (i.e. from url-shortening services like bit.ly) and find out their destination url as well as the body.
The code is mostly ripped from John Nunemaker's blog post “Following Redirects with Net/HTTP” (railstips.org/blog/archives/2009/03/04/following-redirects-with-nethttp/), but wrapped into a Rubygem and with automatic resolving
gem install redirect_follower
Then, either shorthand for the destination url only or for the full response:
$ irb > require 'redirect_follower' > RedirectFollower('http://is.gd/bNZYZ') # Just find out the destination url => 'http://www.taschen.com/pages/en/catalogue/classics/all/06724/facts.byrne_six_books_of_euclid.htm' > redirect = RedirectFollower.new('http://is.gd/bNZYZ') > redirect.url => 'http://www.taschen.com/pages/en/catalogue/classics/all/06724/facts.byrne_six_books_of_euclid.htm' > redirect.body => 'a load of html...' > redirect.response.body => 'a load of html...' # Same as redirect.body > redirect.response => # Full response object from Net::HTTP
Limiting the amount of redirects can be achieved by giving a second parameter to either methods:
RedirectFollower('http://is.gd/bNZYZ', 2) will only follow two redirects before raising RedirectFollower::TooManyRedirects. Same thing for RedirectFollower.new('http://is.gd/bNZYZ', 2). The default amount of redirects is 5.

Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
