I have a problem while acessing google maps from my application, when i send more than 10 requests in loop from java script i get the exception as OVER_QUERY_LIMIT from geoc
Geocoding in the JavaScript API is rate-limited. When you first load the API, you can send 10 requests for address geocoding or 5 for reverse (latlng) geocoding before you get an OVER_QUERY_LIMIT response. When you do, use "exponential backoff" to delay your queries.
