https://docs.traefik.io/v2.2/reference/dynamic-configuration/kv/
in this link all kv is here,but i can't see middleware of tcp
like
traefik/tcp/middlewares/Middleware10/headers/customRequestHeaders/name1
All the available middlewares are for http.
Currently, we don't have middleware support for TCP Routers. It's something we will eventually change tough https://github.com/containous/traefik/issues/6684
does it suport https route?
Sure, you can attach middlewares with HTTPS Routes.
