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....

Valentino

Have you tried setting a

Cache-Control: no-cache, no-store

in your header?

Or an expires header?

or the 'varying URL' trick...

There is some (fairly aged) info at

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 Valentino
