What Is HTTP/2?
HTTP/2 is a version of the HTTP protocol that sends multiple concurrent requests and responses as interleaved streams over a single TCP connection. It compresses headers and supports server push, cutting the overhead and round trips that slowed HTTP/1.1. The semantics of methods and status codes stay the same as earlier HTTP.
Why it matters
HTTP/1.1 limited concurrency per connection, forcing browsers to open many connections and queue requests. HTTP/2 multiplexing removes that bottleneck, improving load time for pages with many assets.
