- Brotli encoding is currently only requested by browsers for https requests, to avoid trouble with bad intermediaries (proxies).
- Dynamically generated content needs it's Content-Type header to be set in order to be compressed.
Brotli browser support
- Firefox: 44+ (on by default)
- Chrome: 49+ (not by default, but can be enabled)
- Edge: 15+ (on by default)
A successfull test with one of the supporting browsers should show an accept-encoding:br in the request headers and subsequently a content-encoding:br in the response headers from the server.
Use the KeyCDN Brotli test tool to check whether Brotli compression is enabled on your website.
