hi guys,

i have problem that is when i m logging out from my application i invalidate the session . but if i click on the browse back button then it is going to the previous page. i also even tried by writing the code

// issue HTTP directives such that this page is not cached
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
%> in my jsp page but it is not working. please help me in ths reagrd it is urgent.

What the back button does is up to the browser. Often it will not retrieve the page anew, but use the copy it has in its cache.
