Based on your reported symptoms, I think the real problem is that you are not actually talking to your server at all! The evidence is that 1) you cannot get a 404 response, and 2) a 200 response does not have the content length and type. Neither of these should be possible ... if you are really talking to the code listed above.

Maybe:

• you are talking to an older version of your code; i.e. something is going wrong in your build / deploy cycle,
• you are (mistakenly) trying to deploy / run your code in a web container (Jetty, Tomcat, etc), or
• your client code / browser is actually talking to a different server due to proxying, an incorrect URL, or something like that.

I suggest that you add some trace printing / logging at appropriate points of your code to confirm that it is actually being invoked.
