+
+The enhancement features `keep alive` `http.Agent`. Support `http` and `https`.
+
+## What's different from original `http.Agent`?
+
+- `keepAlive=true` by default
+- Disable Nagle's algorithm: `socket.setNoDelay(true)`
+- Add free socket timeout: avoid long time inactivity socket leak in the free-sockets queue.
+- Add active socket timeout: avoid long time inactivity socket leak in the active-sockets queue.
+- TTL for active socket.
+
+## Node.js version required
+
+Support Node.js >= `8.0.0`
+
+## Install
+
+```bash
+$ npm install agentkeepalive --save
+```
+
+## new Agent([options])
+
+* `options` {Object} Set of configurable options to set on the agent.
+  Can have the following fields:
+  * `keepAlive` {Boolean} Keep sockets around in a pool to be used by
+    other requests in the future. Default = `true`.
+  * `keepAliveMsecs` {Number} When using the keepAlive option, specifies the initial delay
+    for TCP Keep-Alive packets. Ignored when the keepAlive option is false or undefined. Defaults to 1000.
+    Default = `1000`.  Only relevant if `keepAlive` is set to `true`.
+  * `freeSocketTimeout`: {Number} Sets the free socket to timeout
+    after `freeSocketTimeout` milliseconds of inactivity on the free socket.
+    The default [server-side timeout](https://nodejs.org/api/http.html#serverkeepalivetimeout) is 5000 milliseconds, to [avoid ECONNRESET exceptions](https://medium.com/ssense-tech/reduce-networking-errors-in-nodejs-23b4eb9f2d83), we set the default value to `4000` milliseconds.
+    Only relevant if `keepAlive` is set to `true`.
+  * `timeout`: {Number} Sets the working socket to timeout
+    after `timeout` milliseconds of inactivity on the working socket.
+    Default is `freeSocketTimeout * 2` so long as that value is greater than or equal to 8 seconds, otherwise the default is 8 seconds.
+  * `maxSockets` {Number} Maximum number of sockets to allow per
+    host. Default = `Infinity`.
+  * `maxFreeSockets` {Number} Maximum number of sockets (per host) to leave open
+    in a free state. Only relevant if `keepAlive` is set to `true`.
+    Default = `256`.
+  * `socketActiveTTL` {Number} Sets the socket active time to live, even if it's in use.
+    If not set, the behaviour keeps the same (the socket will be released only when free)
+    Default = `null`.
+
+## Usage
+
+```js
+const http = require('http');
+const Agent = require('agentkeepalive');
+
+const keepaliveAgent = new Agent({
+  maxSockets: 100,
+  maxFreeSockets: 10,
+  timeout: 60000, // active socket keepalive for 60 seconds
+  freeSocketTimeout: 30000, // free socket keepalive for 30 seconds
+});
+
+const options = {
+  host: 'cnodejs.org',
+  port: 80,
+  path: '/',
+  method: 'GET',
+  agent: keepaliveAgent,
+};
+
+const req = http.request(options, res => {
+  console.log('STATUS: ' + res.statusCode);
+  console.log('HEADERS: ' + JSON.stringify(res.headers));
+  res.setEncoding('utf8');
+  res.on('data', function (chunk) {
+    console.log('BODY: ' + chunk);
+  });
+});
+req.on('error', e => {
+  console.log('problem with request: ' + e.message);
+});
+req.end();
+
+setTimeout(() => {
+  if (keepaliveAgent.statusChanged) {
+    console.log('[%s] agent status changed: %j', Date(), keepaliveAgent.getCurrentStatus());
+  }
+}, 2000);
+
+```
+
+### `getter agent.statusChanged`
+
+counters have change or not after last checkpoint.
+
+### `agent.getCurrentStatus()`
+
+`agent.getCurrentStatus()` will return a object to show the status of this agent:
+
+```js
+{
+  createSocketCount: 10,
+  closeSocketCount: 5,
+  timeoutSocketCount: 0,
+  requestCount: 5,
+  freeSockets: { 'localhost:57479:': 3 },
+  sockets: { 'localhost:57479:': 5 },
+  requests: {}
+}
+```
+
+### Support `https`
+
+```js
+const https = require('https');
+const HttpsAgent = require('agentkeepalive').HttpsAgent;
+
+const keepaliveAgent = new HttpsAgent();
+// https://www.google.com/search?q=nodejs&sugexp=chrome,mod=12&sourceid=chrome&ie=UTF-8
+const options = {
+  host: 'www.google.com',
+  port: 443,
+  path: '/search?q=nodejs&sugexp=chrome,mod=12&sourceid=chrome&ie=UTF-8',
+  method: 'GET',
+  agent: keepaliveAgent,
+};
+
+const req = https.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);
+  });
+});
+
+req.on('error', e => {
+  console.log('problem with request: ' + e.message);
+});
+req.end();
+
+setTimeout(() => {
+  console.log('agent status: %j', keepaliveAgent.getCurrentStatus());
+}, 2000);
+```
+
+### Support `req.reusedSocket`
+
+This agent implements the `req.reusedSocket` to determine whether a request is send through a reused socket.
+
+When server closes connection at unfortunate time ([keep-alive race](https://code-examples.net/en/q/28a8069)), the http client will throw a `ECONNRESET` error. Under this circumstance, `req.reusedSocket` is useful when we want to retry the request automatically.
+
+```js
+const http = require('http');
+const Agent = require('agentkeepalive');
+const agent = new Agent();
+
+const req = http
+  .get('http://localhost:3000', { agent }, (res) => {
+    // ...
+  })
+  .on('error', (err) => {
+    if (req.reusedSocket && err.code === 'ECONNRESET') {
+      // retry the request or anything else...
+    }
+  })
+```
+
+This behavior is consistent with Node.js core. But through `agentkeepalive`, you can use this feature in older Node.js version.
