RoutePolicy

Source code of released version | Source code of development version


RoutePolicy, part of Webapp, is a low-level API for declaring the offline access semantics that apply to portions of the app's URL space. This is information is necessary when generating HTML5 Appcache manifests.

For example, DDP uses sockjs to emulate websockets when they are not available. sockjs emulates websockets using HTTP long polling, and it uses URLs under /sockjs to perform this long polling. So the ddp package uses RoutePolicy to declare that the /sockjs route is of type "network" and should always be fetched live from the Internet and never included in the appcache.
