Some clustering solutions such as Kubernetes and Marathon run a proxy on each host that functions as a server-side discovery router. The type of logging you'll see is determined by the proxy mode that you set within HAProxy. Hence the server losses the context of the session and thereby resulting in connection loss. Configuring Computers for RPC over HTTP. The gRPC protobuf data for our success case ended up being one byte short of a multiple of three bytes, so the failure case was an exact multiple of three bytes long. Caching - Before returning the backend server's response to the client, the reverse proxy stores a copy of it locally. BUT HAProxy will obviously loose the source IP transparency because it is a proxy not a router. It greatly simplifies and streamlines network programming such as TCP and UDP socket server. Ambassador Edge Stack is designed so that the author of a given Kubernetes service can easily and flexibly configure how traffic gets routed to the service.
