Express request is called twice

Question

To learn node.js I'm creating a small app that get some rss feeds stored in mongoDB, process them and create a single feed (ordered by date) from these ones.

It parses a list of ~50 rss feeds, with ~1000 blog items, so it's quite long to parse the whole, so I put the following req.connection.setTimeout(60*1000); to get a long enough time out to fetch and parse all the feeds.

Everything runs quite fine, but the request is called twice. (I checked with wireshark, I don't think it's about favicon here).

I really don't get it.

You can test yourself here : http://mighty-springs-9162.herokuapp.com/feed/mde/20 (it should create a rss feed with the last 20 articles about "mde").

The code is here: https://github.com/xseignard/rss-unify

And if we focus on the interesting bits :

I have a route defined like this : app.get('/feed/:name/:size?', topics.getFeed);

And the topics.getFeed is like this :

function getFeed(req, res) {
  // 1 minute timeout to get enough time for the request to be processed
  req.connection.setTimeout(60*1000);   

  var name = req.params.name;
  var callback = function(err, topic) {
  // if the topic has been found
  if (topic) {
    // aggregate the corresponding feeds
    rssAggregator.aggregate(topic, function(err, rssFeed) {
      if (err) {
        res.status(500).send({error: 'Error while creating feed'});
      }
      else {
        res.send(rssFeed);
      }
    },
    req);
  }
  else {
    res.status(404).send({error: 'Topic not found'});
  }};
  // look for the topic in the db
  findTopicByName(name, callback);
}

So nothing fancy, but still, this getFeed function is called twice.

What's wrong there? Any idea?

If you have favicon on your site, remove it and try again. If your problem resolved, refactor your favicon url
