Try http-request set-tos: https://cbonte.github.io/haproxy-dconv/2.2/configuration.html#4.2-http-request%20set-tos (or http-response set-tos https://cbonte.github.io/haproxy-dconv/2.2/configuration.html#4.2-http-response%20set-tos ) I'm not sure the documentation is correct here because documentation says that both http-request/http-response set-tos "packets sent to the client" and http-request probably should say "packets sent to the server" ? -Jarno > Please let me know if this feature has been already implemented or can be > used by any third party tool. -- Jarno Huuskonen
