How to clear browser cache when user log off in asp.net using c#? -


as new in asp.net. in asp.net application in membership in log off on click event using function clearsession(), problem arises after log off if click button on browser forwarding cached page. how clear cache in browser user not view profile if not login

protected void clearsession() {     formsauthentication.signout();     session.clear();     response.cache.setcacheability(httpcacheability.nocache);     response.expiresabsolute = datetime.utcnow.adddays(-1d);     response.expires = -1500;     response.cachecontrol = "no-cache"; }

i think there. need more html headers support browsers. according this article on so these ones work on browsers:

cache-control: no-cache, no-store, must-revalidate pragma: no-cache expires: 0

the full code is:

httpcontext.current.response.addheader("cache-control", "no-cache, no-store, must-revalidate"); httpcontext.current.response.addheader("pragma", "no-cache"); httpcontext.current.response.addheader("expires", "0");
