Edge headers, cache, and compression

Set or delete response headers, cache static prefixes, and compress JSON or HTML.

Console: Edge. Config: edge. REST: GET/PUT /api/edge.

Headers

YAML

edge:
  headers:
    enabled: true
    rules:
      - id: "set-edge-marker"
        operation: "set"
        header: "X-CheeseWAF"
        value: "edge"
        enabled: true
      - id: "remove-origin-leak"
        operation: "delete"
        header: "X-Origin-Secret"
        enabled: true

Use set to add a marker. Use delete to strip origin-only headers before they reach the client.

Cache

YAML

edge:
  cache:
    enabled: true
    mode: "public"
    ttl: 5m
    status_codes: [200, 304]
    path_prefixes: ["/assets/", "/static/"]
    max_body_bytes: 2097152

Only cache prefixes you know are static. Do not cache authenticated HTML.

Compression

YAML

edge:
  compression:
    enabled: true
    algorithms: ["br", "gzip"]
    level: 5
    min_bytes: 1024

content_types in the sample covers text/, JSON, JavaScript, XML, and SVG.
