Description

The HTTP/1.1 protocol can cause TCP race conditions when using keepalive. https://iximiuz.com/en/posts/reverse-proxy-http-keep-alive-and-502s/ does a good job of describing this. HTTP/2 doesn't use keepalive but instead has multiplexing of multiple streams together with a control channel. Testing shows this to be much more reliable, especially at higher concurrency.
