About HTTP/2

HTTP/2 is the second major version of the HTTP protocol, offering significant improvements over HTTP/1.1:

  • Multiplexing: Multiple requests can be sent simultaneously over a single connection
  • Server Push: Servers can proactively send resources to clients
  • Header Compression: Reduces bandwidth usage with HPACK compression
  • Stream Prioritization: Critical resources can be prioritized
  • Binary Protocol: More efficient than text-based HTTP/1.1
  • Better Performance: Faster page loads and reduced latency

HTTP/2 requires HTTPS and is supported by all modern browsers and web servers.
