/**
 * To use the HTTP server and client one must import the `node:http` module.
 *
 * The HTTP interfaces in Node.js are designed to support many features
 * of the protocol which have been traditionally difficult to use.
 * In particular, large, possibly chunk-encoded, messages. The interface is
 * careful to never buffer entire requests or responses, so the
 * user is able to stream data.
 *
 * HTTP message headers are represented by an object like this:
 *
 * ```js
 * { 'content-length': '123',
 *   'content-type': 'text/plain',
 *   'connection': 'keep-alive',
 *   'host': 'mysite.com',
 *   'accept': '*' }
 * ```
 *
 * Keys are lowercased. Values are not modified.
 *
 * In order to support the full spectrum of possible HTTP applications, the Node.js
 * HTTP API is very low-level. It deals with stream handling and message
 * parsing only. It parses a message into headers and body but it does not
 * parse the actual headers or the body.
 *
 * See `message.headers` for details on how duplicate headers are handled.
 *
 * The raw headers as they were received are retained in the `rawHeaders`property, which is an array of `[key, value, key2, value2, ...]`. For
 * example, the previous message header object might have a `rawHeaders`list like the following:
 *
 * ```js
 * [ 'ConTent-Length', '123456',
 *   'content-LENGTH', '123',
 *   'content-type', 'text/plain',
 *   'CONNECTION', 'keep-alive',
 *   'Host', 'mysite.com',
 *   'accepT', '*' ]
 * ```
 * @see [source](https://github.com/nodejs/node/blob/v16.9.0/lib/http.js)

     * An `Agent` is responsible for managing connection persistence

     * until the queue is empty, at which time the socket is either destroyed
     * or put into a pool where it is kept to be used again for requests to the
     * same host and port. Whether it is destroyed or pooled depends on the`keepAlive` `option`.
     *
     * Pooled connections have TCP Keep-Alive enabled for them, but servers may
     * still close idle connections, in which case they will be removed from the
     * pool and a new connection will be made when a new HTTP request is made for
     * that host and port. Servers may also refuse to allow multiple requests
     * over the same connection, in which case the connection will have to be
     * remade for every request and cannot be pooled. The `Agent` will still make
     * the requests to that server, but each one will occur over a new connection.
     *
     * When a connection is closed by the client or the server, it is removed
     * from the pool. Any unused sockets in the pool will be unrefed so as not
     * to keep the Node.js process running when there are no outstanding requests.
     * (see `socket.unref()`).
     *
     * It is good practice, to `destroy()` an `Agent` instance when it is no
     * longer in use, because unused sockets consume OS resources.
     *
     * Sockets are removed from an agent when the socket emits either
     * a `'close'` event or an `'agentRemove'` event. When intending to keep one
     * HTTP request open for a long time without keeping it in the agent, something
     * like the following may be done:
     *
     * ```js
     * http.get(options, (res) => {
     *   // Do stuff
     * }).on('socket', (socket) => {
     *   socket.emit('agentRemove');
     * });
     * ```
     *
     * An agent may also be used for an individual request. By providing`{agent: false}` as an option to the `http.get()` or `http.request()` functions, a one-time use `Agent` with default options
     * will be used
     * for the client connection.
     *
     * `agent:false`:
     *
     * ```js
     * http.get({
     *   hostname: 'localhost',
     *   port: 80,
     *   path: '/',
     *   agent: false  // Create a new agent just for this one request
     * }, (res) => {

     * `http.request()` returns an instance of the {@link ClientRequest} class. The `ClientRequest` instance is a writable stream. If one needs to
     * upload a file with a POST request, then write to the `ClientRequest` object.
     *
     * ```js
     * import http from 'node:http';
     *
     * const postData = JSON.stringify({
     *   'msg': 'Hello World!'
     * });
     *

     *   hostname: 'www.google.com',
     *   port: 80,
     *   path: '/upload',
     *   method: 'POST',
     *   headers: {
     *     'Content-Type': 'application/json',
     *     'Content-Length': Buffer.byteLength(postData)
     *   }
     * };
     *
     * const req = http.request(options, (res) => {
     *   console.log(`STATUS: ${res.statusCode}`);
     *   console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
     *   res.setEncoding('utf8');
     *   res.on('data', (chunk) => {
     *     console.log(`BODY: ${chunk}`);
     *   });
     *   res.on('end', () => {
     *     console.log('No more data in response.');
     *   });

     *   console.error(`problem with request: ${e.message}`);
     * });
     *
     * // Write data to request body
     * req.write(postData);
     * req.end();
     * ```
     *
     * In the example `req.end()` was called. With `http.request()` one
     * must always call `req.end()` to signify the end of the request -
     * even if there is no data being written to the request body.
     *
     * If any error is encountered during the request (be that with DNS resolution,
     * TCP level errors, or actual HTTP parse errors) an `'error'` event is emitted
     * on the returned request object. As with all `'error'` events, if no listeners
     * are registered the error will be thrown.
     *
     * There are a few special headers that should be noted.
     *
     * * Sending a 'Connection: keep-alive' will notify Node.js that the connection to
     * the server should be persisted until the next request.
     * * Sending a 'Content-Length' header will disable the default chunked encoding.
     * * Sending an 'Expect' header will immediately send the request headers.
     * Usually, when sending 'Expect: 100-continue', both a timeout and a listener
     * for the `'continue'` event should be set. See RFC 2616 Section 8.2.3 for more
     * information.
     * * Sending an Authorization header will override using the `auth` option
     * to compute basic authentication.
     *
     * Example using a `URL` as `options`:
     *
     * ```js
     * const options = new URL('http://abc:xyz@example.com');
     *
     * const req = http.request(options, (res) => {
     *   // ...
     * });
     * ```
     *
     * In a successful request, the following events will be emitted in the following
     * order:
     *
     * * `'socket'`
     * * `'response'`
     *    * `'data'` any number of times, on the `res` object
     *    (`'data'` will not be emitted at all if the response body is empty, for
     *    instance, in most redirects)
     *    * `'end'` on the `res` object
     * * `'close'`
     *
     * In the case of a connection error, the following events will be emitted:
     *
     * * `'socket'`
     * * `'error'`
     * * `'close'`
     *
     * In the case of a premature connection close before the response is received,
     * the following events will be emitted in the following order:
     *
     * * `'socket'`
     * * `'error'` with an error with message `'Error: socket hang up'` and code`'ECONNRESET'`
     * * `'close'`
     *
     * In the case of a premature connection close after the response is received,
     * the following events will be emitted in the following order:
     *
     * * `'socket'`
     * * `'response'`
     *    * `'data'` any number of times, on the `res` object
     * * (connection closed here)
     * * `'aborted'` on the `res` object
     * * `'error'` on the `res` object with an error with message`'Error: aborted'` and code `'ECONNRESET'`.
     * * `'close'`
     * * `'close'` on the `res` object
     *
     * If `req.destroy()` is called before a socket is assigned, the following
     * events will be emitted in the following order:
     *
     * * (`req.destroy()` called here)
     * * `'error'` with an error with message `'Error: socket hang up'` and code`'ECONNRESET'`
     * * `'close'`

     * * `'close'`
     * * `'close'` on the `res` object
     *
     * If `req.abort()` is called before a socket is assigned, the following

     *
     * * (`req.abort()` called here)
     * * `'abort'`
     * * `'close'`
     *
     * If `req.abort()` is called before the connection succeeds, the following

     * * `'close'`
     * * `'close'` on the `res` object

     * Setting the `timeout` option or using the `setTimeout()` function will
     * not abort the request or do anything besides add a `'timeout'` event.
