- name: Replay GETs against staging #arbitrary name
  methods: #only replay these requests
  - get
  paths: #replay these paths (use wildcard-notation because I suck at regex)
  - "/api/1/*"
  host_names: #The hostnames to match on
  - api.domain.com
  strip_headers: #remove these headers before replaying the request (list of strings). You can use wildcards such as
  - "X-*" #strip away all X-type headers
  - "User-Agent" #Strip away this and add a new one down below
  - "Content-Length"
  disable_replay_for_user_agent: TraefikReplayR/1.0.0 #You shouldn't normally change this, as it's being use to avoid sending looped messages (which will eventually kill your service)
  add_headers: #add these headers (list of kv pairs)
  - name: X-RiksTV-Synthetic
    value: "true"
  - name: User-Agent #We stripped away the original above (in strip_headers), add a custom one
    value: TraefikReplayR/1.0.0 #should match disable_replay_for_user_agent. Used to avoid resending requests, which will DDOS your service
  replay_factor: 0.01 #1 means one replay-request per original request. 0.1 means 10% of traffic etc. 2 means two replays per incoming request etc.
  replace_hostname: #urls are always lower-cased before the matcher/replacer thing executes use fully qualified things (no wildcards)
    match: api.domain.com
    replace: api-staging.domain.com
