Here is one of the examples on Google Maps https://groups.google.com/a/googleproductforums.com/forum/#!msg/maps/H3S1OG5FVew/XfnBJOHK_jsJ - in that case its a self hosted file.
This: https://groups.google.com/a/googleproductforums.com/forum/#!topic/earth/DV2Iu_fkfuo/discussion is the V2 example - its actully using the KML gadget - but that is using v2. Also using a sites hosted kml file. At the time I replied to that file - I tried using a gadget ported to use v3, and it didnt exhibit the same issue. It stuttered but didnt break. ... from what I seen the 'iw' ajax endpoint starts returning invalid data after a while. So it doesnt appear to be an issue between the browser and Google Maps. Also by that time the KML has been fetched from the server - it displays - and GMaps should have it cached - so its shouldnt be an issue between the origin server and Gmaps. And it happens consistantly for me - every time I view the affected urls. So its not intermittant issue. But that mention of cache - does hint at one possible cause. The cache of the KML on Gmaps server has now expired, and so iw cant return any data for it. I do note that Google Sites says the file shouldnt be cached. No idea if that is new. (the self hosted one is a dynamic script - and doesnt set caching headers) On Sun, Feb 12, 2012 at 8:54 PM, Chris Broadfoot <[email protected]> wrote: > Thanks all for the reports.
