If you enable the Gzip compression feature, Edge Security Acceleration (ESA) points of presence (POPs) return Gzip-compressed files to clients. This reduces the file size, speeds up file transmission, and improves bandwidth utilization.
Usage notes
Gzip or Brotli can compress only files whose size ranges from 1 KB to 10 KB. For files whose size falls outside the range, Gzip or Brotli cannot be used.
Gzip or Brotli can compress files in the following formats: text/xml, text/plain, text/css, application/javascript, application/x-javascript, application/rss+xml, text/javascript, image/tiff, image/svg+xml, application/json, and application/xml.
The Gzip compression feature takes effect on only responses whose client requests carry the
Accept-Encoding: gzipheader.For origin responses that carry the
Content-Encoding: gzipheader, no secondary compression is performed.If you enable the Gzip compression feature and the Brotli compression feature at the same time, the Brotli compression feature takes precedence over the Gzip compression feature.
