ASP.NET WebForms - Real-time notification messages for all users

Question

I have an ASP.NET WebForms webapp hosted on Azure.

Now I want to implement something that I can use to enter a message that will display to all users, such as 'There is a planned application maintenance happening in 30 minutes, please save all work'.

I have no idea if this is even possible or where to start, can anyone point me in the right direction?

We do not know how your application works or the page layout. But, if you have a master page then add code behind that queries a table. If the table has a message then display the message. Placement is up to you. The user will see the message after the next HTTP request.

If you need a quicker message response then write JavaScript application with a timer and AJAX. AJAX calls a Web Method. The Web Method queries the same table above to figure out if there is pending maintenance and returns a message. The JavaScript application writes the message to the page.
