Street map tiles should be cached for a year, if the user's cache settings allow it, but the &v=ap.88 parameter in the URL changes whenever there's a new tile release, so the new tiles get fetched.
Satellite tiles are also configured to be cached for a year, but their URLs contain a &cookie parameter, like &cookie=fzwq2ot2pambCLFzjrK8HQ06SRHYSxPPz6rrU, which changes each time you start a new browser session. So a new tile gets fetched. If you regularly visit the same satellite map tile, there could be many copies of the same tile image with different URLs. Your browser has no way of knowing that URLs with different &cookie parameters are actually the same image. I've no idea why Google do that. The tile servers will happily serve the tiles without the &cookie parameter. -- http://econym.org.uk/gmap The Blackpool Community Church Javascript Team --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
