Test HTTP/3 now!

Question

Nginx 1.25.0 mainline version has been released, featuring experimental HTTP/3 support.

How to test with Webinoly:

• Install Webinoly using the "clean" option: wget -qO weby qrok.es/wy && sudo bash weby -clean
• Set the Nginx "mainline" branch in the Webinoly configuration file: sudo nano /opt/webinoly/webinoly.conf
• Install Nginx and LEMP: sudo stack -lemp
• Create a new site: sudo site example.com -wp
• Add an SSL cert to your site: sudo site example.com -ssl=on
• Add a new listen directive with the quic parameter:

sudo nano /etc/nginx/sites-available/example.com

# Include QUIC support:
listen 443 ssl http2;
listen 443 quic reuseport; # QUIC
listen [::]:443 ssl http2;

• Add a response header telling the browser that an upgrade to QUIC is available.

# Add a custom http header to Webinoly
sudo nano /opt/webinoly/templates/source/custom_header_https_webinoly.data

# Include this two lines:
add_header Alt-Svc 'h3=":$server_port"; ma=86400';
add_header X-protocol $server_protocol always;

# Reload the HTTP headers in Webinoly to changes take effect:
sudo webinoly -custom-headers=reload

• Test it here: https://http3check.net/

And that it! Easy, right?
