Disable Brotli compression

The following example rule will disable Brotli compression for all incoming requests of a given zone. The only available compression algorithm will be Gzip.

When incoming requests match

All incoming requests

Then

Compression options: Custom
Define a custom order for compression types: Gzip

If the client does not support Gzip compression, the response will be uncompressed.

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:

Use the ref field to get stable rule IDs across updates when using Terraform. Adding this field prevents Terraform from recreating the rule on changes. For more information, refer to Troubleshooting in the Terraform documentation.
