Rails 3.1 on Heroku Cedar force HTTP 1.0 response

I have a rails 3.1 app running on heroku’s cedar stack. Now I am having
certificate troubles on IE 8 caused by the HTTP 1.1 response. I know how
to force a HTTP 1.0 on apache, but is there a way to force a HTTP 1.0
response in the rails app. Or another solution?
