Frequently Asked Questions
What is HTTP/2?
HTTP/2 is a major revision of the HTTP protocol that enables multiplexing (multiple requests over one connection), header compression, and server push, significantly improving page load times.
How does HTTP/2 improve performance?
HTTP/2 eliminates head-of-line blocking by multiplexing requests, compresses headers to reduce overhead, and allows server push for proactive resource delivery. Sites typically see 15-50% speed improvements.
Do I need to change my website for HTTP/2?
No code changes needed. HTTP/2 is enabled at the server/CDN level. Most modern hosting providers and CDNs (Cloudflare, CloudFront) support HTTP/2 by default. Your site needs HTTPS for HTTP/2.
