Traefik Proxy Middleware Overview	There are several available middleware in Traefik Proxy used to modify requests or headers, take charge of redirections, add authentication, and so on.

HTTP Middleware Overview

Attached to the routers, pieces of middleware are a means of tweaking the requests before they are sent to your service (or before the answer from the services are sent to the clients).

There are several available middlewares in Traefik, some can modify the request, the headers, some are in charge of redirections, some add authentication, and so on.

Middlewares that use the same protocol can be combined into chains to fit every scenario.

!!! warning "Provider Namespace"

Be aware of the concept of Providers Namespace described in the [Configuration Discovery](../../../install-configuration/providers/overview.md#provider-namespace) section.
It also applies to Middlewares.
