Not sure if you're still monitoring this thread [no HN notifications, eh?], but here's my question:

My get_username() function, say I have this code:

     var server = http.createServer(function(req, res) {
         username = get_username();
         res.writeHead(200);
         res.write("<html>");
         res.write("You are " + username);
         res.end("bye");

This obviously won't work, res.end() gets fired long before my DB query in get_username() finishes. How else would I accomplish what I'm trying to do here other than putting my response stuff in the DB query's callback function?

<Sorry for the newb question, buy what I'm doing: having the response generated inside of the query's callback, seems to be the way most of these node tutorials suggest.>
