When does a TCP connection break in http2?

Question

Computer networks

HTTP 2 has such a feature as multiplexing. Requests are sent within one tcp connection per domain. But it is not clear at what point in time this connection can break the front? Obviously the break happens when the client closes the tab, but is there probably some kind of timeout? For example, if we send a request to the server every 20 seconds, will it be one connection?

Answer 2

Depending on the software. Any fairly mature web server has the appropriate settings, the nginx option above has already been linked.
