Help with force_ssl

Hi, I'd like to force_ssl on all the requests on my application, but not when the subdomain user is foo. How can I do this? The best way would be something like (in the application controller):

force_ssl :unless => proc {|request| request.subdomain == 'foo'}

But from what I read from the doc ( http://api.rubyonrails.org/classes/ActionController/ForceSSL/ClassMethods.html#method-i-force_ssl ) the only options are "only" and "except" for the given actions.

Any hint?

you can use before filter or enviroment.rb file that if request is having sub domain use https"//

for before filter you can use like this

def secure_with_ssl if request.subdomain == 'foo' redirect_to :subdomain => 'foo', :protocol => 'http://' end

put before_filter :secure_with_ssl in application controller
