Can the \'Back\' browser functionality be invoked from a Rails \'Back\' link?
Pay attention to this comment from the user rthbound! As he notes, link_to with the symbol :back does not always generate a “real” back event as if the user clicked on their browser’s Back button. It can also be a resubmit of the action that loaded the current view.
The documentation for Rails 4.2.6 says this about link_to and the :back symbol:
Using a
:backSymbol instead of an options hash will generate a link to the referrer (a JavaScript back link will be used in place of a referrer if none exists).
