推荐答案
您的应用程序的页面
（即检查用户是否已从登录页面登录，并且用户具有正确的密钥），如果他不希望他重定向到登录页面。
您可以对您的应用程序应用正确的身份验证。
Instead of disabling back functionality you should check user's authentication on your application's pages (i.e check whether the user has logged in from login page and user has proper keys or not) if he doesn't that he should be redirected to the login page. You could do this by applying proper authentication on your application.
