As I pointed out in class, you need to make sure that the HTTP response you send from your server includes the correct type, so Argon interprets it correctly. To set the content type of the response in Python in App Engine, I did this:
self.response.headers[‘Content-Type’] = ‘application/vnd.google-earth.kml+xml’
For those wanting to try Google Go, the equivalent code is:
w.Header().Set(“Content-type”, “application/vnd.google-earth.kml+xml”)
where w is the name of your http.ResponseWriter.
