title: connect-busboy: why do I get 404 on fileupload?
body: <p>I have the following code, and when I upload a file, it just starts counting the % in the status bar and once reached 100% I get a 404 error on the file-upload path.</p>
  
  <p>What might be the problem?</p>
  
  <pre><code>&lt;form action="/file-upload", method="post", enctype="multipart/form-data"&gt;
    &lt;input type="file", name="displayImage", id="file"&gt;&lt;/input&gt;
    &lt;input type="submit"&gt;&lt;/input&gt;
  
  app.post('/file-upload', function(req,res,next) {
    var fstream;
    req.pipe(req.busboy);
    req.busboy.on('file', function (fieldname, file, filename) {
      console.log("Uploading: " + filename);
      fstream = fs.createWriteStream(__dirname + '/files/' + filename);
      file.pipe(fstream);
    fstream.on('close', function () {
      res.redirect('back');
    });
  });
  </code></pre>
