## virus-back

The http referer header is unreliable, virus-back uses sessions to track the two previous paths a client has visited. Also provides a convienence method `res.back()` to safely redirect to the previous path or fallback as to prevent a redirect loop.

### Usage

```js

var back = require('virus-back');

app.use(session({

  secret: 'Session Secret'

}));

app.use(back());

app.get('/test', function(req, res) {

  if (!req.isAuthenticated()) {

    return res.back();

  }

});

```

### API

```js

var back = require('virus-back');

```

This middleware depends upon a session middleware or `req.session`, and will populate `req.prevPath` and `req.prevPrevPath`.

#### back(options)

* options {Object}

* options.default {String} The fallback path to populate req.prevPath and req.prevPrevPath, defaults to '/'
