set content type header with rails and apache

Question

I want to send a generated view as a kml file, with the necessary headers(content-type and file expires in)... the use of head gives a 500, and using response.headers has no effect...

What should i do?

Answer 1

You'd need to register the KML mime type. In your config/initializers/mime_types.rb

Mime::Type.register "application/vnd.google-earth.kml", :kml 

Then in your action you can do:

format.kml { ... }

Answer 2

Check out the :content_type option for render.
