title: "Traefik Proxy Middleware Overview"

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

# Middlewares
|
|
|
|
Tweaking the Request
|
|
{: .subtitle }
|
|
|
|
Attached to the routers, pieces of middleware are a means of tweaking the requests before they are sent to your [service](../routing/services/index.md) (or before the answer from the services are sent to the clients).
|
|
|
|
There are several available middleware 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](../providers/overview.md#provider-namespace) section.
|
|
It also applies to Middlewares.
|
|
|
|
## Configuration Example
|
|
|
|
```yaml tab="Docker & Swarm"
|
|
# As a Docker Label
|
|
whoami:
|
|
# A container that exposes an API to show its IP address
|
|
image: traefik/whoami
|
|
labels:
|
|
# Create a middleware named `foo-add-prefix`
|
|
- "traefik.http.middlewares.foo-add-prefix.addprefix.prefix=/foo"
|
|
# Apply the middleware named `foo-add-prefix` to the router named `router1`
|
|
- "traefik.http.routers.router1.middlewares=foo-add-prefix@docker"
|
|
```
|
|
|
|
```yaml tab="IngressRoute"
