Rails Asset Pipeline: Return digest version when non-digest requested

I am providing a snippet for a client to paste into their static html that refers to my application.js file.

As this sits on a page that I do not have control over, and I do not want to ask the client to update their snippet every time I push a release, I am wondering if there is a way to return my digest-application.js version when the normal one is requested to ensure that the browser is getting the the most recent version?

I can set a cache-busting timestamp on the script src, but not sure this is really reliable.

Any thoughts on the best way to handle this?

we are doing something similar for our "public" javascript, which is integrated into a 3rd party web-application.

the way we do this is by creating a symlink on our asset-server during the capistrano deployment that points to the non-digest name of the file. since they are just files on our webserver, the apache does the rest.

I think the must elegant way is doing some Controller to do some redirect 302 to you assets.

You can paste to your client a code link /public-assets/my_assets

In your route create the route :

match '/public-assets/:asset_name' => 'PublicAsset#index'

And create your controller PublicAssetController

class PublicAssetContoller < ApplicationController::Base

  def index
    redirect_to asset_path(params[:asset_name])
  end

end
