Resource Optimizer Extended Compatibility

The standard Resource Optimizer feature is offered as a setting with Adaptive Acceleration. You can enable it to compress and cache resources, such as JavaScript, CSS, and font files. Resource Optimizer Extended Compatibility enhances this version to support the compression of additional file formats and address some compatibility issues.

🚧

As this behavior overrides any standard Resource Optimizer settings, it could also impact Brotli Compression if you have it enabled in the Adaptive Acceleration behavior. Either Resource Optimization Extended Compatibility or Brotli Compression will apply to requests, as you can't use both features. ​​Akamai​ will only execute the last behavior that matches the incoming request.

This behavior is unique to ​Akamai​'s Ion product. Complete details are covered in Ion's documentation.
