The HTTP/4 protocol represents the next generation of the HTTP protocol, designed to improve performance, security, and user experience. Let's dive into what makes HTTP/4 unique and why it matters.
Key Features of HTTP/4
Improved Performance
- HTTP/4 introduces a new binary framing format, which is more efficient than the text-based format used in HTTP/2.
- It reduces the overhead of HTTP headers and allows for multiplexing, enabling concurrent requests over a single connection.
Enhanced Security
- HTTP/4 requires the use of TLS 1.3 or higher, ensuring secure communication between clients and servers.
- It also supports the use of HTTP/3, which uses QUIC (Quick UDP Internet Connections) for improved security and performance.
Improved User Experience
- HTTP/4 includes support for HTTP/3, which allows for lower latency and faster response times.
- It also supports HTTP/2, providing backward compatibility for legacy systems.
