/**
* To use the HTTP server and client one must `require('node:http')`.
*
* 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:
*
* ```json
* { "content-length": "123",
* "content-type": "text/plain",
* "connection": "keep-alive",
* "host": "example.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', 'example.com',
* 'accepT', '*' ]
* ```
* @see [source](https://github.com/nodejs/node/blob/v20.13.1/lib/http.js)

/**
* An `Agent` is responsible for managing connection persistence
* and reuse for HTTP clients. It maintains a queue of pending requests
* for a given host and port, reusing a single socket connection for each
* 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) => {
* // Do stuff with response
* });
* ```
*
* `options` in [`socket.connect()`](https://nodejs.org/docs/latest-v20.x/api/net.html#socketconnectoptions-connectlistener) are also supported.
*
* To configure any of them, a custom {@link Agent} instance must be created.
*
* ```js
* const http = require('node:http');
* const keepAliveAgent = new http.Agent({ keepAlive: true });
* options.agent = keepAliveAgent;
* http.request(options, onResponseCallback)

* Node.js maintains several connections per server to make HTTP requests.
* This function allows one to transparently issue requests.
*
* `url` can be a string or a `URL` object. If `url` is a
* string, it is automatically parsed with `new URL()`. If it is a `URL` object, it will be automatically converted to an ordinary `options` object.
*
* If both `url` and `options` are specified, the objects are merged, with the `options` properties taking precedence.
*
* The optional `callback` parameter will be added as a one-time listener for
* the `'response'` event.
*
* `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';
* import { Buffer } from 'node:buffer';
*
* const postData = JSON.stringify({
* 'msg': 'Hello World!',
* });
*
* const options = {
* 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.');
* });
* });
*
* req.on('error', (e) => {
* 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
* * `'close'`
* * `'error'` on the `res` object with an error with message `'Error: aborted'` and code `'ECONNRESET'`
* * `'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'`, or the error with which `req.destroy()` was called
* * `'close'`
*
* If `req.destroy()` is called before the connection succeeds, the following
* events will be emitted in the following order:
*
* * `'socket'`
* * (`req.destroy()` called here)
* * `'error'` with an error with message `'Error: socket hang up'` and code `'ECONNRESET'`, or the error with which `req.destroy()` was called

*
* If `req.destroy()` is called after the response is received, the following
* events will be emitted in the following order:

* * `'error'` on the `res` object with an error with message `'Error: aborted'` and code `'ECONNRESET'`, or the error with which `req.destroy()` was called
* * `'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

* * (`req.abort()` called here)
* * `'abort'`
* * `'error'` with an error with message `'Error: socket hang up'` and code `'ECONNRESET'`

* * `'error'` on the `res` object with an error with message `'Error: aborted'` and code `'ECONNRESET'`.
* * `'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.
*
* Passing an `AbortSignal` and then calling `abort()` on the corresponding `AbortController` will behave the same way as calling `.destroy()` on the
* request. Specifically, the `'error'` event will be emitted with an error with
* the message `'AbortError: The operation was aborted'`, the code `'ABORT_ERR'` and the `cause`, if one was provided.
