I am filtering requests to determine the browsers used by visitors and eventually give him back a warning about supported browsers ... In the application_controller.rb I have a filter
and a method to test the user_agent ( iE, Firefox, Safari, Chrome and their versions...)
def ensure_browser_supported if html? && cookies[:browser_unsupported] != 'false' && user_agent.unsupported? && session[:browser_unsupported].blank? session[:return_to] = request.fullpath render :template => "/layouts/unsupported_browser", :layout => false end end
Doing some testing on external API request I'll have to answer, I sent a curl request and discover that it obviously failed passing the test as the user agent is "HTTP_USER_AGENT"=>"curl/7.19.7 (universal-apple-darwin10.0) but I guess that a request from a remote server will have another user_agent .... am I right ?
I can add this user agent in the list , but is there any way to differentiate request from browsers and from remote servers before filtering the browsers... what could I check in the request ?
thanks for your feedback
