Module upgrade

HTTP protocol upgrades.

In HTTP it’s not uncommon to convert from one protocol to another. For example HTTP/1.1 can upgrade a connection to websockets using the upgrade header, while HTTP/2 uses a custom handshake. Regardless of the HTTP version, changing protocols always involves some handshake, after which it is turned into a stream of bytes. This module provides primitives for upgrading from HTTP request-response pairs to alternate protocols.

Structs
