when the canvas app is loaded within the iframe nothing is display and on Chrome Firebug Console I see the error:
Refused to display document because display forbidden by X-Frame-Options.
I tried this solution: Overcoming "Display forbidden by X-Frame-Options"
class ApplicationController < ActionController::Base
protect_from_forgery
before_filter :set_xframeoption
def set_xframeoption
response.headers["X-Frame-Options"]='GOFORIT'
end
end
But I have the same error. Any solution?
Thanks
