How to install mod_brotli on Directadmin CentOS 8
Just like gzip, Brotli is also a compression algorithm. It is developed by Google and serves best for text compression. The reason being, it uses a dictionary of common keywords and phrases on both client and server side and thus gives a better compression ratio. The advantage for Brotli over gzip is that it makes use of a dictionary and thus it only needs to send keys instead of full keywords. It is supported by all major browsers. Fewer bytes transferred not only leads to faster page load but also helps in reducing costs of Content Delivery Network (CDN).
