IncomingMessage.prototype.rawHeaders - http - Node documentation
property IncomingMessage.prototype.rawHeaders

Usage in Deno

import { IncomingMessage } from "node:http";

The raw request/response headers list exactly as they were received.

The keys and values are in the same list. It is not a list of tuples. So, the even-numbered offsets are key values, and the odd-numbered offsets are the associated values.

Header names are not lowercased, and duplicates are not merged.

// Prints something like:
//
// [ 'user-agent',
//   'this is invalid because there can be only one',
//   'User-Agent',
//   'curl/7.22.0',
//   'Host',
//   '127.0.0.1:8000',
//   'ACCEPT',
//   '*' ]
console.log(request.rawHeaders);
