Description

episode 23 — Protocol Shorts: HTTP as an Application Bus.

This is the debut of our "Protocol Shorts" series: fast-paced, high-density conversations with one or more expert guests centered around a common theme. In the "HTTP as an application bus" episode, we’re breaking down the tunneling renaissance—specifically the clever 'protocol-within-a-protocol' hacks that are changing the game.

From hijacking H2 CONNECT to run full-duplex WebSockets, to the subtle ways we’re now nesting modern traffic inside older transports, we’re looking at how the network layer is being rewritten from the inside out.
