Support

IIS Brotli is provided "as is". If you encounter any difficulties, please let us know at support@iisbrotli.com. For priority support or SLA enquiries please contact us through sales@iisbrotli.com.

Installation

Installation details are found on the documentation page.

Remarks

  • 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

http://caniuse.com/#feat=brotli

  • Firefox: 44+ (on by default)
  • Chrome: 49+ (not by default, but can be enabled)
  • Edge: 15+ (on by default)

Debugging

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.
