## Follow Redirects

Drop-in replacement for Nodes `http` and `https` that automatically follows redirects.

`follow-redirects` provides [request](https://nodejs.org/api/http.html#http_http_request_options_callback) and [get](https://nodejs.org/api/http.html#http_http_get_options_callback)
 methods that behave identically to those found on the native [http](https://nodejs.org/api/http.html#http_http_request_options_callback) and [https](https://nodejs.org/api/https.html#https_https_request_options_callback)
 modules, with the exception that they will seamlessly follow redirects.

```javascript
var http = require('follow-redirects').http;
var https = require('follow-redirects').https;

http.get('http://bit.ly/900913', function (response) {
  response.on('data', function (chunk) {
    console.log(chunk);
  });
}).on('error', function (err) {
  console.error(err);
});
```

You can inspect the final redirected URL through the `responseUrl` property on the `response`.
If no redirection happened, `responseUrl` is the original request URL.

```javascript
https.request({
  host: 'bitly.com',
  path: '/UHfDGO',
}, function (response) {
  console.log(response.responseUrl);
  // 'http://duckduckgo.com/robots.txt'
});
```

## Options
### Global options
Global options are set directly on the `follow-redirects` module:

```javascript
var followRedirects = require('follow-redirects');
followRedirects.maxRedirects = 10;
followRedirects.maxBodyLength = 20 * 1024 * 1024; // 20 MB
```

The following global options are supported:

- `maxRedirects` (default: `21`) – sets the maximum number of allowed redirects; if exceeded, an error will be emitted.

- `maxBodyLength` (default: 10MB) – sets the maximum size of the request body; if exceeded, an error will be emitted.


### Per-request options
Per-request options are set by passing an `options` object:
