Detect application version change on a single page application

Question

today a question was raised here and I don\'t have an evident answer.

Assume that we concatenate and minify all resource files (CSS and Javascript) and declare them

Answer 1

I decided to add my final thoughts as an answer here too:

We went for a reduced solution for now.

As we have a "proxy service" that is (again for now) the only one that interacts with this application, we added the application version on the http header of all responses. If we receive a newer version, a popup appears notifying the user and a full page refresh is issued...

This solution won't work for applications that don't have their own "private" service.
