What event is triggered when EOF is reached while writing to a stream ?
My code is as follows. and it is as per <http://docs.nodejitsu.com/articles/advanced/streams/how-to-use-fs-create-write-stream>

But surprisingly my 'end' event is never fired. When I checked <http://nodejs.org/api/stream.html#stream_event_end>, I see that writable stream does not have any event on 'end'

---

```
var x = a1.jpg;
var options1 = {'url': url_of_an_image, 'encoding': null};
var r = request(options1).pipe(fs.createWriteStream('/tmp/imageresize/'+x));

r.on('end', function(){
    console.log('file downloaded to ', '/tmp/imageresize/'+x);
}

```

How do I capture the EOF event ?
