Web Hosting General

What is HTTP/2 and HTTP/3 and how do they improve website performance?

HTTP/2 and HTTP/3 are modern versions of the web protocol that dramatically improve performance over the original HTTP/1.1. HTTP/1.1 (1997): One request per TCP connection. Browser opens 6 parallel connections but each requires a round trip. HTTP/2 (2015): Multiplexing — hundreds of requests over ONE connection simultaneously. Header compression (HPACK). Server Push. Result: 30-50% faster than HTTP/1.1. HTTP/3 (2022): Replaces TCP with QUIC (UDP-based). No head-of-line blocking. Faster connection establishment (0-RTT). Performs better on mobile and lossy connections. Both require HTTPS. Connect Quest LiteSpeed web server supports HTTP/2 and HTTP/3 (QUIC) natively on all hosting plans. Verify HTTP/2 is active: curl -I --http2 https://yourdomain.com — look for HTTP/2 200 in response. No configuration needed — Connect Quest enables HTTP/2 by default. HTTP/3 available on LiteSpeed plans. Check your protocol support at connectquest.co.in.
