Following up again on this - now that my cross-thread MessagePort patch is getting close to landing, I am moving forward on the SharedWorker design described earlier in this thread. I think there is still little clarity around the appcache behavior (dimich: are you bring over your "shadow frame" concept to webkit?).
It doesn't seem like it should block the rest of SharedWorker development while we work out the details - I will not expose the appcache APIs for SharedWorkers until we have consensus about how they should work. Let me know if you have any concerns with my approach. I'll add an ENABLE_SHARED_WORKERS flag to control access to these APIs while development proceeds. -atw On Tue, Jun 2, 2009 at 11:43 AM, Michael Nordman <micha...@google.com>wrote: > > As for our implementation - I don't know how appcache is integrated with > the > > loader code. > > We're still working out the details sans workers.
