I worked on struts 2.1 based application.i want when user clicked on logout button, he can't view previous jsp pages by using browser back button.For me, it looks like a situation where i have to reset the browser cache or something like that. I googled a lot about that and i find that delete cache is impossible, but i find some javascript scripts, or use response.setHeaders but none of that worked for me, Any suggestions are welcome.
