Redirect to www for heroku with SSL

If you are using heroku and if you have enabled https then site must be redirected to use www . It means all Rails applications should ensure that "no-www" urls are redirected to "www".

In Rails3 it is pretty easy to do. Here is how it can be done.

1Bigbinary::Application.routes.draw do
2
3  constraints(:host => /^bigbinary.com/) do
4    root :to => redirect("http://www.bigbinary.com")
5    match '/*path', :to => redirect {|params| "http://www.bigbinary.com/#{params[:path]}"}
6  end
7
8end
