Dynamic url_host based on the url format - a private method called a string

I tried to do this for a long time, but I can not get around it.

For URLs ending in .pdf, I want to asset_hostretrieve files locally.

So, I am doing the following in a file development.rb

  config.action_controller.asset_host = Proc.new { |source,request|
    source.format.to_s.match(/pdf/) ? 
        "file://#{Rails.root.join('public')}" :
        "#{request.protocol}#{request.host_with_port}"
  }

But it gives me errors like:

private method `format ', called for" / stylesheets / css3buttons / reset.css? 1304745651 ": String

Question

What is the best way in rails3 to determine the URL request format?

Update I tried source, request.media_typeand request.format, but none of them extracted the PDF!

The logs are shown below. I have added debug statements for each of the three above.

  config.action_controller.asset_host = Proc.new { |source, request|
  print "Source:  " + source 
  print "\n"
  print "request.media_type: " + request.media_type
  print "\n"
  print "request.format:  " + request.format
  print "\n"
  }
