I need a notification system in a web application

Question

I have a web application that our client uses all day. In some cases, I need to stop or restart the application. When I do this, the work of some clients is interrupted, and this makes them nervous.

I want to create a notification system that appears in the application and informs customers about the system shutdown.

How can I create such a system?

Answer 4

( ). - " xxxxxpm ".

When the time comes, you will replace their access to the system (for example, the login page) with the page pointing it down, you have to wait. You either place a new message page with the same name as the username, or configure server redirection automatically. This is how large banks manage.
