Hi @spacewander. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

I think this note based on its position still refers to the connection between Nginx and the Upstream. So I suggest updating it description, removing keepalive_timeout since it's already mentioned on the right of U:

Suggested change

	Note right of P: Repeat if connection is shared until server's keepalive_timeout is hit
	Note right of P: Repeat if connection is shared

Would it make sense to add server's keepalive_timeout to the left of C after "Finishes Response"? This will be similar to Envoy's and HAProxy's diagrams.
