I’ve got a little program that needs to grab favicons from sites using node.js. This works in most cases, but with apple.com, I get errors that I can’t understand or fix:

    var sys= require('sys');
    var fs= require('fs');
    var http = require('http');

    var rurl = http.createClient(80, 'apple.com');
    var requestUrl = 'http://www.apple.com/favicon.ico';
    var request = rurl.request('GET', requestUrl, {"Content-Type": "image/x-icon", "host" : "apple.com" });
    request.end();

    request.addListener('response', function (response)
    {
            response.setEncoding('binary');
            var body = '';
            response.addListener('data', function (chunk) {
                    body += chunk;
            });
            response.addListener("end", function() {
            });
    });

When I make this request, the response is:

<head><body> This object may be found <a HREF="http://www.apple.com/favicon.ico">here</a> </body>

As a result, I’ve modified the above code in just about every way possible with variants of the host name in the client creation step and the url request with ‘www.apple.com’, but typically I just get errors from node as follows:

node.js:63
    throw e;
    ^
Error: Parse Error
    at Client.ondata (http:901:22)
    at IOWatcher.callback (net:494:29)
    at node.js:769:9

Also, I’m not interested in using the google service to grab the favicons.

    This code seems to work for me 

    var sys = require("sys")
  , fs = require("fs")
  , http = require("http");

var client = http.createClient(80, "www.apple.com") // Change of hostname here and below
  , req = client.request( "GET"
                        , "http://www.apple.com/favicon.ico"
                        , {"Host": "www.apple.com"});

req.end();

req.addListener("response", function (res) {
  var body = "";
  res.setEncoding('binary');
  res.addListener("data", function (c) {
    body += c;
  });
  res.addListener("end", function () {
    // Do stuff with body
  });
});
