This limitation blocks from using proxy protocol carrying @mattklein123 Here are the proposed options I could think of with a slight preference to option 2 as it would be more flexible and clear. @alyssawilk @mattklein123 started working on this issue implementing it within the router similar to request_headers_to_add/remove but had a thought - would it be better to implement this as an HTTP filter? This thought occurred to me since the router is already fairly complex and having it be an HTTP filter might be better encapsulated and lower overhead if MARIN3R is a Kubernetes operator to manage a fleet of Envoy proxies within a Kubernetes cluster. Cloud-native high-performance edge/middle/service proxy. the connection from local envoy client was still alive but not functioning as it was not receiving any data from the upstream server. The existing default behaviour will trust RFC1918 IP addresses, but this will be changed in next release. LuaPerRoute provides two ways of overriding the default Lua script:. 6). The goal is, for long-lived streaming requests, to have clients select a new upstream host after max_connection_duration has elapsed, and therefore balance new and existing client connections as the backing application scales out.
