Frequently Asked Questions

โ“ What is HTTP/2?

HTTP/2 is a major revision of HTTP that enables multiplexing (multiple requests over one connection), header compression, and server push.

โ“ Does HTTP/2 require HTTPS?

Technically no, but all major browsers only support HTTP/2 over TLS/HTTPS. You need an SSL certificate.

โ“ Is HTTP/3 better than HTTP/2?

HTTP/3 uses QUIC (UDP-based) instead of TCP, offering faster connections, better mobile performance, and improved loss recovery.
