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

Copy
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 in your dynamic configuration as explained here. 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.

Copy
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.
