Prevent Users from using the BACK Button. To do this we must actually put a tiny piece of JavaScript on the Page we do not want users to go back to. In other words, once they leave the page, if they attempt to return they will be forced back to the page they left.

Disable-Back-Button.js

/* [Begin] Prevent User from Returning to this Page after Submit */
function disableBack() {
    window.history.forward()
}

window.onload = disableBack();
window.onpageshow = function (event) { if (event.persisted) disableBack() }
/* [End] Prevent User from Returning to this Page after Submit */
