HTTP Digest Client

Hacked together snippet for talking to HTTP servers that employ digest authentication.

Disclaimer

Only tested against one server and spec is not followed fully. It works for me and for what I am doing.

Usage

var digest = require('http-digest-client')('username', 'password');
var postData = {message: 'Hello'};
var req = digest.request({
    host: 'hostname.com',
    path: '/path.json',
    port: 80,
    method: 'POST',
    headers: {
       "User-Agent": "Simon Ljungberg",
       "Content-Type": "application/json"
     } // Set any headers you want
  }, function responseCallback(res) {
    res.on('data', function (data) {
      console.log(data.toString());
    });
    res.on('error', function (err) {
      console.log('oh noes');
    });
  }, function requestCallback(req) {
      req.write(postData);
      req.end();
   });
// Uncomment the line below, in case the end point demands that the post should be include in the first request.
// req.write(postData)
req.end();
```

The digest client will make one reques to the server, authentication response
is calculated and then the request is made again. Hopefully you will then
be authorized.

## Writing to `req`

I haven't yet figured out a way to write data to the final `req` object.
Mainly because I haven't really needed it. Feel free to suggest solutions! :)
