Automatic Gzip compression

Document updated on May 18, 2023

KrakenD Enterprise compresses with gzip all traffic returned to the client when the request contains an Accept-Encoding: gzip header.

The gzip is not applied when the header is missing or when the Accept-Encoding header contains a text/event-stream value.

Gzip compression is unrelated to decompression when consuming content from your services. Decompression is also done automatically, but in all KrakenD flavors, not only Enterprise.

When the content is successfully compressed, the response contains a "Content-Encoding: gzip" header.

Gzip configuration

The gzip is always on unless you disable it in the router section as follows:

{
  "version": 3,
  "extra_config": {
    "router": {
      "disable_gzip": true
    }
  }
}
