My application caches the configuration and route data for a particular agency (to be precise, I build a database from it). I'm looking for some mechanism to check/test when my locally cached data needs to be updated. I've seen older discussions from some years ago w/Nextbus suggesting that simply supporting the "Last-Modified" field in the HTTP response header would do the trick. But I see no evidence this has been implemented. Any recent insight here would be welcomed.
As an aside: Perhaps because the NextBus API is relatively straightforward, there is no longer much discussion here? Or have nextbus api discussions in effect moved to another forum (if so which?). There does not seem to be an obvious way to contact NextBus directly regarding technical questions (and I can imagine supporting the public feeds could become a nightmare).
