Module: Turbolinks::XHRHeaders

Included in:
Controller
Defined in:
lib/turbolinks/xhr_headers.rb

Overview

Intercepts calls to _compute_redirect_to_location (used by redirect_to) for two purposes.

  1. Corrects the behavior of redirect_to with the :back option by using the X-XHR-Referer

request header instead of the standard Referer request header.

  1. Stores the return value (the redirect target url) to persist through to the redirect

request, where it will be used to set the X-XHR-Redirected-To response header. The Turbolinks script will detect the header and use replaceState to reflect the redirected url.
