Modern HTTP features

This example demonstrates the dependency-free modern HTTP features in fh:

• 103 Early Hints with custom Link attributes
• General informational responses with SendInformational
• PushResource helpers for stylesheets, scripts, and fonts
• RFC 9218 Priority request parsing and response generation
• HTTP/2 support for Early Hints and resource push, with HTTP/1.1 Early Hints fallback

Run it from the repository root:

go run ./examples/http-modern

Then inspect the responses:

curl -i http://localhost:8084/early-hints
curl -i http://localhost:8084/resources
curl -i -H 'Priority: u=1, i' http://localhost:8084/priority

The priority endpoint returns the parsed request priority and emits a Priority response header. Use an HTTP/2-capable client against a TLS listener to inspect HTTP/2 informational responses and push behavior; the plain listener is useful for observing the HTTP/1.1 103 Early Hints fallback.
