+#### idle_timeout
+
+In HTTP2 server:
+
+Specifies the time until idle clients should be closed with a GOAWAY frame. PING frames are not considered as activity.
+
+In HTTP2 client:
+
+Specifies the period of time after which a health check will be performed using a ping frame if no frames have been received on the connection. Please note that a ping response is considered a received frame, so if there is no other traffic on the connection, the health check will be executed every interval. If the value is zero, no health check will be performed.
+
+Zero is used by default.
+
+#### ping_timeout
+
+In HTTP2 client:
+
+Specifies the timeout duration after sending a PING frame, within which a response must be received. If a response to the PING frame is not received within the specified timeout duration, the connection will be closed. The default timeout duration is 15 seconds.
