Enable HTTP/2 or HTTP/3

Modern HTTP protocols significantly reduce the impact of latency and allow multiple resources to be downloaded simultaneously over a single connection, leading to much faster page loads.

Quick Reference

Enable HTTP/2 or HTTP/3 for request multiplexing
Eliminate the need for resource concatenation
Reduce overhead with header compression

Check

Verify that the server is serving resources over HTTP/2 or HTTP/3 using browser DevTools or online checkers.

Fix

Enable HTTP/2 or HTTP/3 in your web server (Nginx, Apache) or via a CDN/load balancer.

Explain

Explain the advantages of HTTP/2 and HTTP/3 over HTTP/1.1, such as multiplexing and header compression.

Code Review

Review the routes, assets, and loading behavior that affect Enable HTTP/2 or HTTP/3. Flag exact files, requests, or rendering steps that add unnecessary network, CPU, or layout cost, and describe the measurement method used to confirm the issue.

For full implementation details, code examples, and framework-specific guidance, see references/rule.md.
