Alt-Svc for the people

A presentation at Curl up 2018 in in Stockholm, Sweden by Lucas Pardue

Alt-Svc is short for HTTP Alternative Services. It's a bit like DNS and a bit like HTTP redirects with some added oomph. It's a way for an Origin to nominate an Alternative host, protocol and port. It's the only way specified to bootstrap a new HTTP/QUIC connection. It's many things to many people. It isn't implemented in many User Agents beyond browsers.

I've said too much, I havn't said enough.

This presentation discusses Alt-Svc features and foot guns. Play Alt-Svc minesweeper to determine where YOU'LL go wrong when trying to implement Alt-Svc in your application!
