Curling header returns HTTP status 404

[Jingwei Liu]

demo app:

var app = require('koa')();
var route = require("koa-route");

app.use(route.get("/", function *(next){
  this.body = 'Hello World';
}));

app.listen(8080);

When fetching HTTP-header with curl -I, the server returns

# curl -I http://localhost:8080
HTTP/1.1 404 Not Found
X-Powered-By: koa
Date: Thu, 21 Aug 2014 02:20:00 GMT

Meanwhile, a browser visit or a normal curl yields the sane result

#curl -i --raw http://localhost:8080
HTTP/1.1 200 OK
X-Powered-By: koa
Content-Type: text/plain; charset=utf-8
Content-Length: 11
Date: Thu, 21 Aug 2014 02:57:46 GMT
Connection: keep-alive

Hello World

The 'problem' is that you handle only GET type of requests using route.get. The -I uses HEAD type of request. So if you want to handle this, then use

app.use(router.head('/', function *(){
  this.set('X-Response-message', 'Welcome to my HEAD');
  this.status = 200;
}));

ah yeah this is usually handled by routers but koajs/route is pretty low level, however since koa core handles HEAD we should probably add HEAD here, definitely a necessity for every server even if it's a little weird since this is no longer 1:1
