# Rewrite Body

Rewrite body is a middleware plugin for [Traefik](https://github.com/traefik/traefik) which rewrites the HTTP response body by replacing a search regex by a replacement string.

## Configuration

### Static

```toml

[pilot]

  token = "xxxx"

[experimental.plugins.rewritebody]

  modulename = "github.com/traefik/plugin-rewritebody"

  version = "v0.3.1"

```

### Dynamic

To configure the `Rewrite Body` plugin you should create a [middleware](https://doc.traefik.io/traefik/middlewares/overview/) in 

your dynamic configuration as explained [here](https://doc.traefik.io/traefik/middlewares/overview/).

The following example creates  and uses the `rewritebody` middleware plugin to replace all `foo` occurrences by `bar` in the HTTP response body.

If you want to apply some limits on the response body, you can chain this middleware plugin with the [Buffering middleware](https://doc.traefik.io/traefik/middlewares/http/buffering/) from Traefik.

```toml

[http.routers]

  [http.routers.my-router]

    rule = "Host(`localhost`)"

    middlewares = ["rewrite-foo"]

    service = "my-service"

[http.middlewares]

  [http.middlewares.rewrite-foo.plugin.rewritebody]

    # Keep Last-Modified header returned by the HTTP service.

    # By default, the Last-Modified header is removed.

    lastModified = true

    # Rewrites all "foo" occurences by "bar"

    [[http.middlewares.rewrite-foo.plugin.rewritebody.rewrites]]

      regex = "foo"

      replacement = "bar"

[http.services]

  [http.services.my-service]

    [http.services.my-service.loadBalancer]

      [[http.services.my-service.loadBalancer.servers]]

        url = "http://127.0.0.1"

```
