I have a small application that serves documents (typically PDF and word). I''m using the file_column plug-in to update and manage the documents. I''m serving the documents via Mongrel (this is a small intranet application). I have one main problem: users'' browsers are caching the documents, and therefore new revisions of documents are not being downloaded by everyone. I want to send an HTTP header Cache-Control statement limiting the life of the documents to tens of minutes. Can I do this within my Rails application? If not, I''ll serve the documents via another server where I can set the cache life at the folder level. However, it would be easier to manage the system if the setting could be made within the Rails app. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you''re serving the document from an action, you can add any header
you want by putting it in the headers[] hash:
class MyController < ActionController::Base
def file
headers[''Cache-Control''] = ''no-cache''
headers[''Pragma''] = ''no-cache''
# send file
end
end
