HTTP Deceiver (with fixes)

const net = require('net');
const http = require('http');
const Deceiver = require('http-deceiver-fixes');

// Mock a socket for the HTTP parser to attach to
const mockSocket = new net.Socket({ readable: true, writable: true });
mockSocket.write = () => true; // Suppress actual writing
mockSocket.resume(); // Ensure data flows for parsing

// Create an http.IncomingMessage instance, which internally initializes an HTTP parser
const incoming = new http.IncomingMessage(mockSocket);

// Create a Deceiver instance, wrapping the internal parser of the IncomingMessage.
// The Deceiver intercepts and allows manipulation of the parsing process.
// Note: `incoming._parser` relies on Node.js internals and might change.
const deceiver = new Deceiver(incoming._parser);

// Example raw HTTP request string, potentially containing multiple messages
// or data that requires custom parsing logic.
const rawHttpRequest = [
  'GET /path1 HTTP/1.1',
  'Host: localhost',
  'Content-Length: 0',
  '',
  'POST /path2 HTTP/1.1', // A second, potentially pipelined or unexpected request
  'Host: localhost',
  'Content-Length: 7',
  'User-Agent: DeceiverAgent',
  '',
  'PAYLOAD',
