Summary

The blog post discusses the implementation and benefits of HPACK, a new header compression algorithm used in HTTP/2 connections. Unlike previous algorithms like DEFLATE, HPACK is resilient to attacks such as CRIME due to its use of static and dynamic dictionaries, along with Huffman encoding. The blog post provides detailed explanations on how HPACK works for both request and response headers, demonstrating significant compression rates that lead to reduced bandwidth usage and improved performance.
