+
+`readIdleTimeout` is the timeout after which a health check using ping frame will be carried out
+if no frame is received on the HTTP/2 connection.
+Note that a ping response will be considered a received frame,
+so if there is no other traffic on the connection,
+the health check will be performed every `readIdleTimeout` interval.
+If zero, no health check is performed.
