Usage

Add the plugin in your static configuration

# Static configuration
experimental:
  plugins:
    cookiesmanager:
      moduleName: github.com/theoguidoux/cookiesmanager
      version: "0.0.1"

Use the plugin in your dynamic configuration like this

# Dynamic configuration

http:
  routers:
    my-router:
      rule: host(`demo.localhost`)
      service: service-foo
      entryPoints:
        - web
      middlewares:
        - cookiesmanager

  services:
   service-foo:
      loadBalancer:
        servers:
          - url: http://127.0.0.1:5000
  
  middlewares:
    cookiesmanager:
      plugin:
        cookiesmanager:
          adder:
            - name: cookie1
              value: "foo=bar"
            - name: "SameSite"
              value: "none"
          remover:
            - name: "cookie2"
              value: "foo=bar"

The middleware defined above would make it so that requests to service-foo have cookie1 containing foo=bar, SameSite containing none and cookie2 not containing foo=bar.
