How do you add a custom HTTP response header in Rails?

I'm looking to add custom HTTP response headers to a Ruby on Rails app that is currently hosted on Heroku.

Solution

  • Use:

    response.headers['HEADER NAME'] = 'HEADER VALUE'

    either in a specific method or to a before_filter method of your application controller depending on whether you need this to be added in a specific or to all of your responses.

    UPDATE for Rails 5 - February 24th, 2018

    As noted by @BrentMatzelle in the comments, for Rails 5:

    response.set_header('HEADER NAME', 'HEADER VALUE')
