单击浏览器的后退按钮后如何避免后退？

Question

I am using jsp and jquery.

After logging in, the home page is displayed, but when I click on the back button of browser, it show me log in page again.

When I click on the back button, I want it to redirect to the home page, like GMail does.

Answer 1

Simply check if someone is logged in at the login page, and if so redirect to the homepage. No magic necessary here.
