Specification

Summary

This feature adds support for using designated previous responses, as an external dictionary for Brotli-compressing HTTP responses.

Blink component

Blink>Network

Motivation

If the browser and server share a dictionary, using the dictionary for compression can significantly reduce the amount of data transferred. This is especially useful for incremental library updates, or when browsing multiple pages that have a lot of common parts in their files.
