It'd be interesting if the limit was in some way discoverable. I understand that it's not a game, but it would be immensely helpful if the back-off message was advisory rather than punitive. I can imagine this being expressed as HTTP headers that let you know how long to wait until your next request, or how close a client is to being blocked. I can adapt to whatever the current limitations are, but only if they're communicated in a machine-parseable way. -mike. ---------------------------------------------------------------- michal migurski- [email protected] 415.558.1610 _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
