How to pipe attachments from couchdb - without losing nice caching effects [nano]

gistfile1.js

var couchconfig = {
  hostname: "localhost"
}

var nano = require("./nano/nano.js")("http://" + couchconfig.hostname + ":5984"),
	db = nano.use("nano-test"),
	express = require("express");
	
var app = express.createServer();

app.get('/', function(req, res){
	req.headers.host = couchconfig.host;
	nano.request({
		db: "nano-test",
		doc: "test",
		att: "latest-xkcd.png",
		headers: req.headers
	}).pipe(res);
});

app.listen(3000);

Note, as of this date this example only works with the modified version of nano, where headers can be passed to nano.request()... (see https://github.com/streunerlein/nano)

A pull request to the original nano is in progress...
