compression

The compression keyword enables you to define if the application router compresses text resources before sending them.

By default, resources larger than 1KB are compressed. If you need to change the compression size threshold, for example, to “2048 bytes”, you can add the optional property “minSize”: <size_in_KB>, as illustrated in the following example.

Sample Code:

{
  "compression": {
      "minSize": 2048
  }
}

You can disable compression in the following ways:

• Global

  Within the compression section add "enabled": false

• Front end

  The client sends a header “Accept-Encoding” which does not include “gzip”.

• Back end

  The application sends a header “Cache-Control” with the “no-transform” directive.
