# Rewrite Response Headers

Rewrite response headers is a middleware plugin for Traefik which rewrites the HTTP response headers by replacing a search regex by a replacement string.

## Configuration

### Static

```yaml

pilot:

  token: "xxxx"

experimental:

  plugins:

    rewriteResponseHeaders:

      moduleName: github.com/jamesmcroft/traefik-plugin-rewrite-response-headers

      version: "v1.0.0"

```

### Dynamic

To configure the Rewrite Response Headers plugin you should create a [middleware](https://docs.traefik.io/middlewares/overview/) in your dynamic configuration as explained [here](https://doc.traefik.io/traefik/middlewares/overview/). The following example creates and uses the `rewriteResponseHeaders` middleware plugin to replace a custom `Operation-Location` header which provides a `http://` URL with a `https://` URL.

```yaml

http:

  services:

    serviceRoot:

      loadBalancer:

        servers:

          - url: "http://localhost:8080"

  middlewares:

    rewrite-operation-location-header:

      plugin:

        rewriteResponseHeaders:

          rewrites:

            - header: "Operation-Location"

              regex: "^http://(.+?)/(.+)$"

              replacement: "https://{RequestHost}/$2"

  routers:

    routerRoot:

      rule: "PathPrefix(`/`)"

      service: "serviceRoot"

      middlewares:

        - "rewrite-operation-location-header"

```

> [!NOTE]

> This plugin includes a `{RequestHost}` token which can be used in the `replacement` string to include the original request host in the replaced header value. **It is not required to use this token**.
