Preventing page caching in Opera
I am trying to prevent Opera from caching pages with no luck. Could someone let me know what the secret is to get this to work. Here are the following headers that I am using. Thanks!rsp.addHeader("Cache-Control", "max-age=1");
rsp.setHeader("Cache-Control", "no-cache");
rsp.setHeader("Pragma", "no-cache");
rsp.setDateHeader("Expires", "-1");
rsp.addHeader("Cache-Control", "no-store");
rsp.addHeader("Cache-Control", "must-revalidate");
rsp.addHeader("Cache-Control", "private");
Even i face the same issue. I believe, Somebody from Opera has to help us. It might be a bug in Opera.
If user clicks browser back button and it goes to previos page(cached page). Though i set cache-control as No-cache. I don't want user to click back button. I just added the following line in my jsp file inside <script></script> tag. It worked. It might be useful to you
function noBack(param){
window.history.forward();
alert(param);
}
//noBack("call from noback inline method");
window.onload=noBack("call from onload method");
window.onpageshow=function(evt){if(evt.persisted)noBack("call from onpageshow method")}
window.onunload=function(){void(0)}
