+# httpntlm
+
+__httpntlm__ is a Node.js library to do HTTP NTLM authentication
+
+It's a port from the Python libary [python-ntml](https://code.google.com/p/python-ntlm/)
+
+## Install
+
+You can install __httpntlm__ using the Node Package Manager (npm):
+
+    npm install httpntlm
+
+## How to use
+
+```js
+var httpntlm = require('httpntlm');
+
+httpntlm.get({
+    url: "https://someurl.com",
+    username: 'm$',
+    password: 'stinks',
+    workstation: 'choose.something',
+    domain: ''
+}, function (err, res){
+    if(err) return err;
+
+    console.log(res.headers);
+    console.log(res.body);
+});
+```
+
+It supports __http__ and __https__.
+
+## Options
+
+- `url:`      _{String}_   URL to connect. (Required)
+- `username:` _{String}_   Username. (Required)
+- `password:` _{String}_   Password. (Required)
+- `workstation:` _{String}_ Name of workstation or `''`.
+- `domain:`   _{String}_   Name of domain or `''`.
+
+You can also pass along all other options of [httpreq](https://github.com/SamDecrock/node-httpreq), including custom headers, cookies, body data, ... and use POST, PUT or DELETE instead of GET.
+
+## Advanced
+
+If you want to use the NTLM-functions yourself, you can access the ntlm-library like this (https example):
+
+```js
+var ntlm = require('httpntlm').ntlm;
+var async = require('async');
+var httpreq = require('httpreq');
+var HttpsAgent = require('agentkeepalive').HttpsAgent;
+var keepaliveAgent = new HttpsAgent();
+
+var options = {
+    url: "https://someurl.com",
+    username: 'm$',
+    password: 'stinks',
+    workstation: 'choose.something',
+    domain: ''
+};
+
+async.waterfall([
+    function (callback){
+        var type1msg = ntlm.createType1Message(options);
+
+        httpreq.get(options.url, {
+            headers:{
+                'Connection' : 'keep-alive',
+                'Authorization': type1msg
+            },
+            agent: keepaliveAgent
+        }, callback);
+    },
+
+    function (res, callback){
+        if(!res.headers['www-authenticate'])
+            return callback(new Error('www-authenticate not found on response of second request'));
+
+        var type2msg = ntlm.parseType2Message(res.headers['www-authenticate']);
+        var type3msg = ntlm.createType3Message(type2msg, options);
+
+        setImmediate(function() {
+            httpreq.get(options.url, {
+                headers:{
+                    'Connection' : 'Close',
+                    'Authorization': type3msg
+                },
+                allowRedirects: false,
+                agent: keepaliveAgent
+            }, callback);
+        });
+    }
+], function (err, res) {
+    if(err) return console.log(err);
+
+    console.log(res.headers);
+    console.log(res.body);
+});
+```
+
+## Download binary files
+
+```javascript
+httpntlm.get({
+    url: "https://someurl.com/file.xls",
+    username: 'm$',
+    password: 'stinks',
+    workstation: 'choose.something',
+    domain: '',
+    binary: true
+}, function (err, response) {
+    if(err) return console.log(err);
+    fs.writeFile("file.xls", response.body, function (err) {
+        if(err) return console.log("error writing file");
+        console.log("file.xls saved!");
+    });
+});
+```

(Required)\n- `username:` _{String}_   Username. (Required)\n- `password:` _{String}_   Password. (Required)\n- `workstation:` _{String}_ Name of workstation or `''`.\n- `domain:`   _{String}_   Name of domain or `''`.\n\nYou can also pass along all other options of [httpreq](https://github.com/SamDecrock/node-httpreq), including custom headers, cookies, body data, ... and use POST, PUT or DELETE instead of GET.\n\n## Advanced\n\nIf you want to use the NTLM-functions yourself, you can access the ntlm-library like this (https example):\n\n```js\nvar ntlm = require('httpntlm').ntlm;\nvar async = require('async');\nvar httpreq = require('httpreq');\nvar HttpsAgent = require('agentkeepalive').HttpsAgent;\nvar keepaliveAgent = new HttpsAgent();\n\nvar options = {\n    url: \"https://someurl.com\",\n    username: 'm$',\n    password: 'stinks',\n    workstation: 'choose.something',\n    domain: ''\n};\n\nasync.waterfall([\n    function (callback){\n        var type1msg = ntlm.createType1Message(options);\n\n        httpreq.get(options.url, {\n            headers:{\n                'Connection' : 'keep-alive',\n                'Authorization': type1msg\n            },\n            agent: keepaliveAgent\n        }, callback);\n    },\n\n    function (res, callback){\n        if(!res.headers['www-authenticate'])\n            return callback(new Error('www-authenticate not found on response of second request'));\n\n        var type2msg = ntlm.parseType2Message(res.headers['www-authenticate']);\n        var type3msg = ntlm.createType3Message(type2msg, options);\n\n        setImmediate(function() {\n            httpreq.get(options.url, {\n                headers:{\n                    'Connection' : 'Close',\n                    'Authorization': type3msg\n                },\n                allowRedirects: false,\n                agent: keepaliveAgent\n            }, callback);\n        });\n    }\n], function (err, res) {\n    if(err) return console.log(err);\n\n    console.log(res.headers);\n    console.log(res.body);\n});\n```\n\n## Download binary files\n\n```javascript\nhttpntlm.get({\n    url: \"https://someurl.com/file.xls\",\n    username: 'm$',\n    password: 'stinks',\n    workstation: 'choose.something',\n    domain: '',\n    binary: true\n}, function (err, response) {\n    if(err) return console.log(err);\n    fs.writeFile(\"file.xls\", response.body, function (err) {\n        if(err) return console.log(\"error writing file\");\n        console.log(\"file.xls saved!\");\n    });\n});\n```\n\n## More information\n\n* [python-ntlm](https://code.google.com/p/python-ntlm/)\n* [NTLM Authentication Scheme for HTTP](http://www.innovation.ch/personal/ronald/ntlm.html)\n* [LM hash on Wikipedia](http://en.wikipedia.org/wiki/LM_hash)\n\n\n## License (MIT)\n\nCopyright (c) Sam Decrock <https://github.com/SamDecrock/>\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and associated documentation files (the \"Software\"), to deal\nin the Software without restriction, including without limitation the rights\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\ncopies of the Software, and to permit persons to whom the Software is\nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in\nall copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

+  console.log(res.headers);
+  console.log(res.body);
+  console.log(res.cookies);
+});
+```
+
+## How to use

+
+---------------------------------------
+### httpreq.get(url, [options], callback)
+<a name="get"></a>
+
+__Arguments__
+ - url: The url to connect to. Can be http or https.
+ - options: (all are optional) The following options can be passed:
+    - parameters: an object of query parameters
+    - headers: an object of headers
+    - cookies: an array of cookies
+    - auth: a string for basic authentication. For example `username:password`
+    - binary: true/false (default: false), if true, res.body will a buffer containing the binary data
+    - allowRedirects: (default: __true__ , only with httpreq.get() ), if true, redirects will be followed
+    - maxRedirects: (default: __10__ ). For example 1 redirect will allow for one normal request and 1 extra redirected request.
+    - timeout: (default: __none__ ). Adds a timeout to the http(s) request. Should be in milliseconds.
+    - proxy, if you want to pass your request through a http(s) proxy server:
+        - host: eg: "192.168.0.1"
+        - port: eg: 8888
+        - protocol: (default: __'http'__ ) can be 'http' or 'https'
+     - rejectUnauthorized: validate certificate for request with HTTPS. [More here](http://nodejs.org/api/https.html#https_https_request_options_callback)
+ - callback(err, res): A callback function which is called when the request is complete. __res__ contains the headers ( __res.headers__ ), the http status code ( __res.statusCode__ ) and the body ( __res.body__ )
+
+__Example without options__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.get('http://www.google.com', function (err, res){
+  if (err) return console.log(err);
+
+  console.log(res.statusCode);
+  console.log(res.headers);
+  console.log(res.body);
+});
+```
+
+__Example with options__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.get('http://posttestserver.com/post.php', {
+  parameters: {
+    name: 'John',
+    lastname: 'Doe'
+  },
+  headers:{
+    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:18.0) Gecko/20100101 Firefox/18.0'
+  },
+  cookies: [
+    'token=DGcGUmplWQSjfqEvmu%2BZA%2Fc',
+    'id=2'
+  ]
+}, function (err, res){
+  if (err){
+    console.log(err);
+  }else{
+    console.log(res.body);
+  }
+});
+```

+### httpreq.post(url, [options], callback)
+<a name="post"></a>
+
+__Arguments__
+ - url: The url to connect to. Can be http or https.
+ - options: (all are optional) The following options can be passed:
+    - parameters: an object of post parameters (content-type is set to *application/x-www-form-urlencoded; charset=UTF-8*)
+    - json: if you want to send json directly (content-type is set to *application/json*)
+    - files: an object of files to upload (content-type is set to *multipart/form-data; boundary=xxx*)
+    - body: custom body content you want to send. If used, previous options will be ignored and your custom body will be sent. (content-type will not be set)
+    - headers: an object of headers
+    - cookies: an array of cookies
+    - auth: a string for basic authentication. For example `username:password`
+    - binary: true/false (default: __false__ ), if true, res.body will be a buffer containing the binary data
+    - allowRedirects: (default: __false__ ), if true, redirects will be followed
+    - maxRedirects: (default: __10__ ). For example 1 redirect will allow for one normal request and 1 extra redirected request.
+    - encodePostParameters: (default: __true__ ), if true, POST/PUT parameters names will be URL encoded.
+    - timeout: (default: none). Adds a timeout to the http(s) request. Should be in milliseconds.
+    - proxy, if you want to pass your request through a http(s) proxy server:
+        - host: eg: "192.168.0.1"
+        - port: eg: 8888
+        - protocol: (default: __'http'__ ) can be 'http' or 'https'
+    - rejectUnauthorized: validate certificate for request with HTTPS. [More here](http://nodejs.org/api/https.html#https_https_request_options_callback)
+ - callback(err, res): A callback function which is called when the request is complete. __res__ contains the headers ( __res.headers__ ), the http status code ( __res.statusCode__ ) and the body ( __res.body__ )
+
+__Example without extra options__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.post('http://posttestserver.com/post.php', {
+  parameters: {
+    name: 'John',
+    lastname: 'Doe'
+  }
+}, function (err, res){
+  if (err){
+    console.log(err);
+  }else{
+    console.log(res.body);
+  }
+});
+```
+
+__Example with options__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.post('http://posttestserver.com/post.php', {
+  parameters: {
+    name: 'John',
+    lastname: 'Doe'

+}, function (err, res){
+  if (err){
+    console.log(err);
+  }else{
+    console.log(res.body);
+  }
+});
+```
+
+---------------------------------------
+### httpreq.put(url, [options], callback)
+<a name="put"></a>
+
+Same options as [httpreq.post(url, [options], callback)](#post)
+
+---------------------------------------
+<a name="delete" />
+### httpreq.delete(url, [options], callback)
+
+Same options as [httpreq.post(url, [options], callback)](#post)
+
+---------------------------------------
+<a name="options" />
+### httpreq.options(url, [options], callback)
+
+Same options as [httpreq.get(url, [options], callback)](#get) except for the ability to follow redirects.
+
+---------------------------------------
+<a name="upload" />
+### Uploading files
+
+You can still use ```httpreq.uploadFiles({url: 'url', files: {}}, callback)```, but it's easier to just use POST (or PUT):
+
+__Example__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.post('http://posttestserver.com/upload.php', {
+  parameters: {
+    name: 'John',
+    lastname: 'Doe'
+  },
+  files:{
+    myfile: __dirname + "/testupload.jpg",
+    myotherfile: __dirname + "/testupload.jpg"
+  }
+}, function (err, res){

+<a name="binary"></a>
+### Downloading a binary file
+To download a binary file, just add __binary: true__ to the options when doing a get or a post.
+
+__Example__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.get('https://ssl.gstatic.com/gb/images/k1_a31af7ac.png', {binary: true}, function (err, res){
+  if (err){
+    console.log(err);
+  }else{
+    fs.writeFile(__dirname + '/test.png', res.body, function (err) {
+      if(err)
+        console.log("error writing file");
+    });
+  }
+});
+```
+
+---------------------------------------
+<a name="download"></a>
+### Downloading a file directly to disk
+To download a file directly to disk, use the download method provided.
+
+Downloading is done using a stream, so the data is not stored in memory and directly saved to file.
+
+__Example__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.download(
+  'https://ssl.gstatic.com/gb/images/k1_a31af7ac.png',
+  __dirname + '/test.png'
+, function (err, progress){
+  if (err) return console.log(err);
+  console.log(progress);
+}, function (err, res){
+  if (err) return console.log(err);
+  console.log(res);
+});
+
+```
+---------------------------------------
+<a name="custombody"></a>
+### Sending a custom body
+Use the body option to send a custom body (eg. an xml post)
+
+__Example__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.post('http://posttestserver.com/post.php',{
+  body: '<?xml version="1.0" encoding="UTF-8"?>',
+  headers:{
+    'Content-Type': 'text/xml',
+  }},
+  function (err, res) {
+    if (err){
+      console.log(err);
+    }else{
+      console.log(res.body);
+    }
+  }
+);
+```
+
+---------------------------------------
+<a name="proxy"></a>
+### Using a http(s) proxy
+
+__Example__
+
+```js
+var httpreq = require('httpreq');
+
+httpreq.post('http://posttestserver.com/post.php', {
+  proxy: {
+    host: '10.100.0.126',
+    port: 8888
+  }
+}, function (err, res){
+  if (err){
+    console.log(err);
+  }else{
+    console.log(res.body);
+  }
+});
+```
+
+---------------------------------------
+### httpreq.doRequest(options, callback)
+<a name="dorequest"></a>
+
+httpreq.doRequest is internally used by httpreq.get() and httpreq.post(). You can use this directly. Everything is stays the same as httpreq.get() or httpreq.post() except that the following options MUST be passed:
+- url: the url to post the files to
+- method: 'GET', 'POST', 'PUT' or 'DELETE'

Can be http or https.\n - options: (all are optional) The following options can be passed:\n    - parameters: an object of query parameters\n    - headers: an object of headers\n    - cookies: an array of cookies\n    - auth: a string for basic authentication. For example `username:password`\n    - binary: true/false (default: false), if true, res.body will a buffer containing the binary data\n    - allowRedirects: (default: __true__ , only with httpreq.get() ), if true, redirects will be followed\n    - maxRedirects: (default: __10__ ). For example 1 redirect will allow for one normal request and 1 extra redirected request.\n    - timeout: (default: __none__ ). Adds a timeout to the http(s) request. Should be in milliseconds.\n    - proxy, if you want to pass your request through a http(s) proxy server:\n        - host: eg: \"192.168.0.1\"\n        - port: eg: 8888\n        - protocol: (default: __'http'__ ) can be 'http' or 'https'\n     - rejectUnauthorized: validate certificate for request with HTTPS. [More here](http://nodejs.org/api/https.html#https_https_request_options_callback)\n - callback(err, res): A callback function which is called when the request is complete. __res__ contains the headers ( __res.headers__ ), the http status code ( __res.statusCode__ ) and the body ( __res.body__ )\n\n__Example without options__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.get('http://www.google.com', function (err, res){\n  if (err) return console.log(err);\n\n  console.log(res.statusCode);\n  console.log(res.headers);\n  console.log(res.body);\n});\n```\n\n__Example with options__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.get('http://posttestserver.com/post.php', {\n  parameters: {\n    name: 'John',\n    lastname: 'Doe'\n  },\n  headers:{\n    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:18.0) Gecko/20100101 Firefox/18.0'\n  },\n  cookies: [\n    'token=DGcGUmplWQSjfqEvmu%2BZA%2Fc',\n    'id=2'\n  ]\n}, function (err, res){\n  if (err){\n    console.log(err);\n  }else{\n    console.log(res.body);\n  }\n});\n```\n---------------------------------------\n### httpreq.post(url, [options], callback)\n<a name=\"post\"></a>\n\n__Arguments__\n - url: The url to connect to.

If used, previous options will be ignored and your custom body will be sent. (content-type will not be set)\n    - headers: an object of headers\n    - cookies: an array of cookies\n    - auth: a string for basic authentication.

[More here](http://nodejs.org/api/https.html#https_https_request_options_callback)\n - callback(err, res): A callback function which is called when the request is complete. __res__ contains the headers ( __res.headers__ ), the http status code ( __res.statusCode__ ) and the body ( __res.body__ )\n\n__Example without extra options__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.post('http://posttestserver.com/post.php', {\n  parameters: {\n    name: 'John',\n    lastname: 'Doe'\n  }\n}, function (err, res){\n  if (err){\n    console.log(err);\n  }else{\n    console.log(res.body);\n  }\n});\n```\n\n__Example with options__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.post('http://posttestserver.com/post.php', {\n  parameters: {\n    name: 'John',\n    lastname: 'Doe'\n  },\n  headers:{\n    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:18.0) Gecko/20100101 Firefox/18.0'\n  },\n  cookies: [\n    'token=DGcGUmplWQSjfqEvmu%2BZA%2Fc',\n    'id=2'\n  ]\n}, function (err, res){\n  if (err){\n    console.log(err);\n  }else{\n    console.log(res.body);\n  }\n});\n```\n\n---------------------------------------\n### httpreq.put(url, [options], callback)\n<a name=\"put\"></a>\n\nSame options as [httpreq.post(url, [options], callback)](#post)\n\n---------------------------------------\n<a name=\"delete\" />\n### httpreq.delete(url, [options], callback)\n\nSame options as [httpreq.post(url, [options], callback)](#post)\n\n---------------------------------------\n<a name=\"options\" />\n### httpreq.options(url, [options], callback)\n\nSame options as [httpreq.get(url, [options], callback)](#get) except for the ability to follow redirects.\n\n---------------------------------------\n<a name=\"upload\" />\n### Uploading files\n\nYou can still use ```httpreq.uploadFiles({url: 'url', files: {}}, callback)```, but it's easier to just use POST (or PUT):\n\n__Example__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.post('http://posttestserver.com/upload.php', {\n  parameters: {\n    name: 'John',\n    lastname: 'Doe'\n  },\n  files:{\n    myfile: __dirname + \"/testupload.jpg\",\n    myotherfile: __dirname + \"/testupload.jpg\"\n  }\n}, function (err, res){\n  if (err) throw err;\n});\n```\n\n---------------------------------------\n<a name=\"binary\"></a>\n### Downloading a binary file\nTo download a binary file, just add __binary: true__ to the options when doing a get or a post.\n\n__Example__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.get('https://ssl.gstatic.com/gb/images/k1_a31af7ac.png', {binary: true}, function (err, res){\n  if (err){\n    console.log(err);\n  }else{\n    fs.writeFile(__dirname + '/test.png', res.body, function (err) {\n      if(err)\n        console.log(\"error writing file\");\n    });\n  }\n});\n```\n\n---------------------------------------\n<a name=\"download\"></a>\n### Downloading a file directly to disk\nTo download a file directly to disk, use the download method provided.\n\nDownloading is done using a stream, so the data is not stored in memory and directly saved to file.\n\n__Example__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.download(\n  'https://ssl.gstatic.com/gb/images/k1_a31af7ac.png',\n  __dirname + '/test.png'\n, function (err, progress){\n  if (err) return console.log(err);\n  console.log(progress);\n}, function (err, res){\n  if (err) return console.log(err);\n  console.log(res);\n});\n\n```\n---------------------------------------\n<a name=\"custombody\"></a>\n### Sending a custom body\nUse the body option to send a custom body (eg. an xml post)\n\n__Example__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.post('http://posttestserver.com/post.php',{\n  body: '<?xml version=\"1.0\" encoding=\"UTF-8\"?>',\n  headers:{\n    'Content-Type': 'text/xml',\n  }},\n  function (err, res) {\n    if (err){\n      console.log(err);\n    }else{\n      console.log(res.body);\n    }\n  }\n);\n```\n\n---------------------------------------\n<a name=\"proxy\"></a>\n### Using a http(s) proxy\n\n__Example__\n\n```js\nvar httpreq = require('httpreq');\n\nhttpreq.post('http://posttestserver.com/post.php', {\n  proxy: {\n    host: '10.100.0.126',\n    port: 8888\n  }\n}, function (err, res){\n  if (err){\n    console.log(err);\n  }else{\n    console.log(res.body);\n  }\n});\n```\n\n---------------------------------------\n### httpreq.doRequest(options, callback)\n<a name=\"dorequest\"></a>\n\nhttpreq.doRequest is internally used by httpreq.get() and httpreq.post(). You can use this directly. Everything is stays the same as httpreq.get() or httpreq.post() except that the following options MUST be passed:\n- url: the url to post the files to\n- method: 'GET', 'POST', 'PUT' or 'DELETE'\n\n## Donate\n\nIf you like this module or you want me to update it faster, feel free to donate.

+# nodemailer-fetch
+
+Fetches HTTP URL contents for [nodemailer](https://github.com/nodemailer/nodemailer).
+
+[![Build Status](https://secure.travis-ci.org/nodemailer/nodemailer-fetch.svg)](http://travis-ci.org/nodemailer/nodemailer-fetch)
+<a href="http://badge.fury.io/js/nodemailer-fetch"><img src="https://badge.fury.io/js/nodemailer-fetch.svg" alt="NPM version" height="18"></a>
+
+## Usage
+
+```javascript
+var fetch = require('nodemailer-fetch');
+fetch('http://www.google.com/').pipe(process.stdout);
+```
+
+The method takes the destination URL as the first and optional options object as the second argument.
+
+The defaults are the following:
+
+  * Default method is GET
+  * Basic auth is supported
+  * Up to 5 redirects are followed (Basic auth gets lost after first redirect)
+  * gzip is handled if present
+  * Cookies are supported
+  * No shared HTTP Agent
+  * Invalid SSL certs are allowed. Can be overwritten with the `tls` option
+
+### options
+
+Possible options are the following:
+
+  * **userAgent** a string defining the User Agent of the request (by default not set)
+  * **cookie** a cookie string or an array of cookie strings where a cookie is the value used by 'Set-Cookie' header
+  * **maxRedirects** how many redirects to allow (defaults to 5, set to 0 to disable redirects entirely)
+  * **method** HTTP method to use, defaults to GET (if `body` is set defaults to POST)
+  * **body** HTTP payload to send. If the value is an object it is converted to an *x-www-form-urlencoded* payload, other values are passed as is. Unlike authentication data payload and method is preserved between redirects
+  * **contentType** optional content type for the HTTP payload. Defaults to *x-www-form-urlencoded*. If the value is `false` then Content-Type header is not set
+  * **tls** optional object of TLS options
+  * **timeout** (milliseconds) sets timeout for the connection. Returns an error if timeout occurs
+  * **headers** custom headers as an object where key is the header key and value is either a string or an array of strings for multiple values
+
+  ```javascript
+  var fetch = require('nodemailer-fetch');
+  fetch('http://www.google.com/', {
+      cookie: [
+          'cookie_name1=cookie_value1',
+          'cookie_name2=cookie_value2; expires=Sun, 16 Jul 3567 06:23:41 GMT',
+      ],
+      userAgent: 'MyFetcher/1.0'
+  }).pipe(process.stdout);
+  ```
+
+> Cookies are domain specific like normal browser cookies, so if a redirect happens to another domain, then cookies are not passed to it, HTTPS-only cookies are not passed to HTTP etc.
