I know two way of doing this.
1. in servlet code use
response.setHeader("Pragma","No-Cache");
response.setHeader("Cache-Control","no-Cache");
response.setDateHeader("Expires", 0 );
2. Basicaly do the same but only with <META ..> keyword in HTML
I do not remember exactly format of <META> but can look it up if you
need.
You need all 3of them for different versions of browsers. If yourtarget is
one browser you can leave only those which is working with that browser.
