In Javascript, how do I "clear" the back (history -1)?

Question

When the user loads the page, I immediately do a window redirect to another location.

The problem is, when the user clicks back, it'll go back to the page which does the redirect.

Can I "cancel" the history of the previous page? So that when the user clicks back, it goes back TWO pages instead?

Answer 1

Instead of using window.location = url; to redirect,

try:

window.location.replace(url); 

after using replace() the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.

Answer 2

You can use location.replace to replace the current location entry (the redirect page) with the new one (the target). That requires that you do the redirection via JavaScript rather than with meta tags or a 302. E.g.:

// In the redirecting page location.replace("path/to/target/page");
