Web Performance Calendar » Getting Real (small) With Compression Dictionaries

Compression dictionary transport is a relatively new feature in HTTP that allows for using custom compression dictionaries to improve the compression of HTTP responses. The results can be pretty dramatic, with responses anywhere from 60-90+% smaller than using the best non-dictionary compression currently available. The feature has been under experimentation in Chrome over the last two years and shipped to stable earlier this year in Chrome 130. This article will discuss how to implement and ship a production-quality implementation that uses dictionary compression on the edge without having to modify an existing application (based on what we learned with several implementations that have shipped or are getting ready to ship).
