Head-of-Line Blocking in HTTP/2 Although HTTP/2 uses “frames”, “streams”, and “multiplexing” to eliminate “head-of-line blocking”, these techniques are applied at the application layer. However, at the lower layer, specifically in the TCP protocol, “head-of-line blocking” can still occur. TCP has a special “packet retransmission” mechanism to ensure reliable transmission. Lost packets must wait for retransmission … Read more
Author | Frontend Craftsman Editor | Zhang Zhidong, Wang Wenjing HTTP/2 has significantly improved web performance compared to HTTP/1.1, requiring only an upgrade to this protocol to reduce many of the performance optimizations that were previously necessary. Of course, compatibility issues and how to gracefully downgrade are likely among the reasons it is not yet … Read more

Better understand how each version of HTTP works. In the early 1990s, Tim Berners-Lee and his team at CERN worked together to define four fundamental components of the internet: Hypertext document format (HTML) Data transfer protocol (HTTP) A web browser for viewing hypertext (the first browser, WorldWideWeb) A server for transmitting data (an early version … Read more
