The **reverse‑http** package implements the client side of the Reverse HTTP protocol (draft‑lentczner‑rhttp). It lets a Node.js application open an outbound HTTP (or HTTPS) request to a server that supports the “Upgrade: PTTH/1.0” handshake, then receive inbound HTTP requests over that same connection as if it were a regular `http.Server`. It’s aimed at developers who need to expose services behind firewalls or NATs without requiring inbound ports, using a simple Node.js API.
