addr

addr
====

Get the remote address of a request, with reverse-proxy support


Usage
=====

``bash
$ npm install addr
`

addr(req, [proxies])

- req: an http.ServerRequest object.
- proxes: an array of IP addresses of trusted proxies. If specified and
the request doesn't come from one of these addresses, the X-Forwarded-For
header will not be honored.
- Returns: Remote IP address of the request, taken from the X-Forwarded-For
header if it exists and the request is coming from a trusted proxy.

Example
=======

`javascript
var addr = require('addr')
, http = require('http')
, port = 3000
, proxies = ['127.0.0.1']
;

http.createServer(function(req, res) {
res.writeHead(200, {'Content-Type': 'application/json'});
res.write(JSON.stringify({addr: addr(req, proxies)}));
res.end();
}).listen(port, function() {
console.log('test server running on port ' + port);
});
``
