Overview

After enabling the page compression feature, you can compress most static files, effectively reducing the size of transmitted content by users and enhancing the delivery effect.

Currently, page compression supports Brotli Compression and Gzip Compression two ways.

Brotli is an open-sourced new compression algorithm. After the Brotli compression feature is enabled, when the CDN node returns the requested resource, it performs Brotli compression on text files such as html, js and css.

File types that support compression include: text/plain、application/x-javascript、text/css、application/xml、application/rss+xml、application/xmltext、image/tiff、text/javascript、text/html、text/xml、application/javascript、image/svg+xml、application/json、text/json.

Notes

Support compression simultaneous selections of Gzip and Brotli and their independent compressions; once the Brotli compression is selected to start, the Brotli is in priority; If the origin server has already compressed the content, CDN service will not compress it again.
