Use only Brotli compression for a specific path

Dashboard

The following example rule will configure only Brotli compression for a specific URI path.

When incoming requests match

• Custom filter expression:

  • URI Path equals /download/assets.tar

Then

• Compression options: Custom
• Define a custom order for compression types: Brotli

Since the rule configuration does not include Auto at the end of the custom algorithms list, the response will be uncompressed if the web visitor does not support Brotli.

API

The following example sets the rules of an existing entry point ruleset (with ID {ruleset_id}) for the http_response_compression phase to a single compression rule, using the Update a zone ruleset operation:

curl --request PUT \
https://api.cloudflare.com/client/v4/zones/{zone_id}/rulesets/{ruleset_id} \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Content-Type: application/json" \
--data '{
  "rules": [
    {
      "expression": "http.request.uri.path eq \"/download/assets.tar\"",
      "action": "compress_response",
      "action_parameters": {
        "algorithms": [
          { "name": "brotli" }
        ]
      }
    }
  ]
}'
