Reset session if user click back button in browser

Rails

Dear all

Can rails reset session if user click the back button in browser?

say,

  1. go to 应用宝官网-全网最新最热手机应用游戏下载
  2. Search something and display the result
  3. go to http://another_server.com
  4. click back button, I still can see the result in browser, but I don’t
    want to see the browser cache…

Any idea to implement this feature? Please advise. Million thanks…

Have you tried setting a

Cache-Control: no-cache, no-store

in your header?

Or an expires header?

or the ‘varying URL’ trick…

Thanks for your reply

I put the following code in my application controller

before_filter :set_cache_buster

def set_cache_buster
    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”
end

It will not cache the dynamic content if back button is pressed, but the
session is still here…

Many thanks
