Instance Method Details

#call(env) ⇒ Object

The “non_ruby_request” variable denotes a request which doesn’t call a Ruby script. This might be a CSS, static HTML, image, media, or JavaScript request.

This check is in place so that if you’re using this gem with multiple Rack apps running in the same application context, you won’t have static resources resetting the currency selection due to requests going into the main app instead of a sub-app.
