This enables putting the manifest files on a CDN.

Status: Rejected
Change Description: no spec change
Rationale: It would also enable a hostile open wifi access point to permanently hijack facebook.com to point to evil.example.net, which seems, to put it mildly, problematic.
Comment 2 michaeln 2011-11-11 20:44:58 UTC
Reopening in the hopes of gathering more input about why the SOP for this is a problem and what might be done to resolve it.
Comment 3 Ian 'Hixie' Hickson 2011-12-03 22:23:56 UTC
Reassigning to michaeln as per comment 2. If you gather actionable input, please don't hesitate to reassign this to me so I can study it further.
Comment 4 Tobie Langel 2012-01-24 22:14:21 UTC
This was an attempt at solving use-case #2 here: http://www.w3.org/community/fixing-appcache/2012/01/18/appcache_use_cases/#use_case_2

Allow an application hosted on a cluster of servers to be easily updated
An application is hosted on a cluster of servers behind a non-sticky load balancer. It is updated daily. Even though all servers are not updated instantly and two versions of the application co-exist for a while, it is possible to update the application without risking to have an out-of sync version of the application (e.g. manifest file and assets of the latest version combined with a Master Entry of the previous version) or to need to invalidate the cache to avoid such issues.

Probably would have been more useful to provide the use case upfront rather that potential solutions.

Ian, why could a wireless not do that anyway over HTTP without TLS? And if there is TLS, there is no problem to begin with.

You still need CORS because of the update events (I think). You also need a new crossorigin attribute on <html> to control the details.
