How do I get the url stored in ":back"?
It's easy, and common, to redirect to :back in Rails.
However, how do I access the actual URL stored, or represented by ":back"?

Rails uses request.headers["Referer"] and raises an error if it's nil.

request.env['HTTP_REFERER'] in your controller, but be aware, that this can always be nil
