How to prevent browser from caching a page in rails

I used devise for authentication in my rails project. After I signed out; I clicked the back button in the browser; Oh!!! the browser was showing the previous page from which I clicked ‘sign out’.  I tested this and found that the browser is caching the page.

I used firebug to analyze the project page(s). I found that the

no-cahe is added

To add ‘no-cache’, I added the following lines @ the application_controller.rb file

before_filter :set_no_cache

and the function

def set_no_cache
response.headers["Cache-Control"] = "no-cache, no-store, max-age=0, must-revalidate"
response.headers["Pragma"] = "no-cache"
response.headers["Expires"] = "Fri, 01 Jan 1990 00:00:00 GMT"

Restarted the server and found that after I signout and hit ‘back button’ of the browser; the page is redirected to the sign_in page. [ I have configured devise to redirect to sign_in when the session is not valid].

Hope this helps rails users like me.

and I analyzed the rails project page(s) using firebug andThe firebug analyzed results

no-cache implemeted
