By default, Tornado puts a Cache-Control: public header on any file served by a StaticFileHandler. How can this be changed to Cache-Control: no-cache?

The accepted answer does not work for Chrome. Subclass StaticFileHandler using the following:

class MyStaticFileHandler(tornado.web.StaticFileHandler):
    def set_extra_headers(self, path):
        # Disable cache
        self.set_header('Cache-Control', 'no-store, no-cache, must-revalidate, max-age=0')
