Tracks the number of requests received by Varnish over a persistent connection. 
Over an HTTP/2 connection, tracks the number of multiplexed requests.

With HTTP/1.1, persistent connections are the default.
A persistent connection is one that remains open for a period of time and can be reused for \"several requests\", saving the need for a new TCP handshake for every request.

With HTTP/2, concurrent requests are allowed over a single connection, which is called multiplexing.
