missing `keep alive` `http.Agent`. Support `http` and `https`.\n\n## What's different from original `http.Agent`?\n\n- `keepAlive=true` by default\n- Disable Nagle's algorithm: `socket.setNoDelay(true)`\n- Add free socket timeout: avoid long time inactivity socket leak in the free-sockets queue.\n- Add active socket timeout: avoid long time inactivity socket leak in the active-sockets queue.\n\n## Install\n\n```bash\n$ npm install agentkeepalive --save\n```\n\n## new Agent([options])\n\n* `options` {Object} Set of configurable options to set on the agent.\n Can have the following fields:\n * `keepAlive` {Boolean} Keep sockets around in a pool to be used by\n other requests in the future. Default = `true`.\n * `keepAliveMsecs` {Number} When using the keepAlive option, specifies the initial delay\n for TCP Keep-Alive packets. Ignored when the keepAlive option is false or undefined. Defaults to 1000.\n Default = `1000`. Only relevant if `keepAlive` is set to `true`.\n * `freeSocketKeepAliveTimeout`: {Number} Sets the free socket to timeout\n after `freeSocketKeepAliveTimeout` milliseconds of inactivity on the free socket.\n Default is `15000`.\n Only relevant if `keepAlive` is set to `true`.\n * `timeout`: {Number} Sets the working socket to timeout\n after `timeout` milliseconds of inactivity on the working socket.\n Default is `freeSocketKeepAliveTimeout * 2`.\n * `maxSockets` {Number} Maximum number of sockets to allow per\n host. Default = `Infinity`.\n * `maxFreeSockets` {Number} Maximum number of sockets (per host) to leave open\n in a free state. Only relevant if `keepAlive` is set to `true`.\n Default = `256`.\n * `socketActiveTTL` {Number} Sets the socket active time to live, even if it's in use.\n If not setted the behaviour continues the same (the socket will be released only when free)\n Default = `null`.\n\n## Usage\n\n```js\nconst http = require('http');\nconst Agent = require('agentkeepalive');\n\nconst keepaliveAgent = new Agent({\n maxSockets: 100,\n maxFreeSockets: 10,\n timeout: 60000,\n freeSocketKeepAliveTimeout: 30000, // free socket keepalive for 30 seconds\n});\n\nconst options = {\n host: 'cnodejs.org',\n port: 80,\n path: '/',\n method: 'GET',\n agent: keepaliveAgent,\n};\n\nconst req = http.request(options, res => {\n console.log('STATUS: ' + res.statusCode);\n console.log('HEADERS: ' + JSON.stringify(res.headers));\n res.setEncoding('utf8');\n res.on('data', function (chunk) {\n console.log('BODY: ' + chunk);\n });\n});\nreq.on('error', e => {\n console.log('problem with request: ' + e.message);\n});\nreq.end();\n\nsetTimeout(() => {\n if (keepaliveAgent.statusChanged) {\n console.log('[%s] agent status changed: %j', Date(), keepaliveAgent.getCurrentStatus());\n }\n}, 2000);\n\n```\n\n### `getter agent.statusChanged`\n\ncounters have change or not after last checkpoint.\n\n### `agent.getCurrentStatus()`\n\n`agent.getCurrentStatus()` will return a object to show the status of this agent:\n\n```js\n{\n createSocketCount: 10,\n closeSocketCount: 5,\n timeoutSocketCount: 0,\n requestCount: 5,\n freeSockets: { 'localhost:57479:': 3 },\n sockets: { 'localhost:57479:': 5 },\n requests: {}\n}\n```\n\n### Support `https`\n\n```js\nconst https = require('https');\nconst HttpsAgent = require('agentkeepalive').HttpsAgent;\n\nconst keepaliveAgent = new HttpsAgent();\n// https://www.google.com/search?q=nodejs&sugexp=chrome,mod=12&sourceid=chrome&ie=UTF-8\nconst options = {\n host: 'www.google.com',\n port: 443,\n path: '/search?q=nodejs&sugexp=chrome,mod=12&sourceid=chrome&ie=UTF-8',\n method: 'GET',\n agent: keepaliveAgent,\n};\n\nconst req = https.request(options, res => {\n console.log('STATUS: ' + res.statusCode);\n console.log('HEADERS: ' + JSON.stringify(res.headers));\n res.setEncoding('utf8');\n res.on('data', chunk => {\n console.log('BODY: ' + chunk);\n });\n});\n\nreq.on('error', e => {\n console.log('problem with request: ' + e.message);\n});\nreq.end();\n\nsetTimeout(() => {\n console.log('agent status: %j', keepaliveAgent.getCurrentStatus());\n}, 2000);\n```\n\n## [Benchmark](https://github.com/node-modules/agentkeepalive/tree/master/benchmark)\n\nrun the benchmark:\n\n```bash\ncd benchmark\nsh start.sh\n```\n\nIntel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz\n\nnode@v0.8.9\n\n50 maxSockets, 60 concurrent, 1000 requests per concurrent, 5ms delay\n\nKeep alive agent (30 seconds):\n\n```js\nTransactions: 60000 hits\nAvailability: 100.00 %\nElapsed time: 29.70 secs\nData transferred: 14.88 MB\nResponse time: 0.03 secs\nTransaction rate: 2020.20 trans/sec\nThroughput: 0.50 MB/sec\nConcurrency: 59.84\nSuccessful transactions: 60000\nFailed transactions: 0\nLongest transaction: 0.15\nShortest transaction: 0.01\n```\n\nNormal agent:\n\n```js\nTransactions: 60000 hits\nAvailability: 100.00 %\nElapsed time: 46.53 secs\nData transferred: 14.88 MB\nResponse time: 0.05 secs\nTransaction rate: 1289.49 trans/sec\nThroughput: 0.32 MB/sec\nConcurrency: 59.81\nSuccessful transactions: 60000\nFailed transactions: 0\nLongest transaction: 0.45\nShortest transaction: 0.00\n```\n\nSocket created:\n\n```\n[proxy.js:120000] keepalive, 50 created, 60000 requestFinished, 1200 req/socket, 0 requests, 0 sockets, 0 unusedSockets, 50 timeout\n{\" <10ms\":662,\" <15ms\":17825,\" <20ms\":20552,\" <30ms\":17646,\" <40ms\":2315,\" <50ms\":567,\" <100ms\":377,\" <150ms\":56,\" <200ms\":0,\" >=200ms+\":0}\n----------------------------------------------------------------\n[proxy.js:120000] normal , 53866 created, 84260 requestFinished, 1.56 req/socket, 0 requests, 0 sockets\n{\" <10ms\":75,\" <15ms\":1112,\" <20ms\":10947,\" <30ms\":32130,\" <40ms\":8228,\" <50ms\":3002,\" <100ms\":4274,\" <150ms\":181,\" <200ms\":18,\" >=200ms+\":33}\n```\n\n## License\n\n```\n(The MIT License)\n\nCopyright(c) node-modules and other contributors.\nCopyright(c) 2012 -
