Please don't do this! It loses state, it borks the page when the network connection is lost (laptop closed and opened somewhere else), it interrupts whatever I was doing on the page, ...
That's the 1997 way.
What's wrong with it?
It reloads the whole page.
That's what I said. Isn't it relevant for tasks that take a long time to complete?
Forcing a reload is never relevant. If it's a very long operation, use a modal popup, or hide the refreshing part of the page, but you should never force a reload.
