I'm confused over whether the API usage limits of 2500 geocoding requests per day ( http://code.google.com/apis/maps/documentation/geocoding/#Limits ) and 25,000 Javascript maps per day ( http://code.google.com/apis/maps/faq.html#usagelimits ) are referring to the requests generated by the website visitor or by the web server serving the page that contains the map or makes the geocoding requests?
