Does Ember routing fall back to using a hash if browser doesn't support the History API?

Question

Ember documentation states that it can be set to use the History API for routing rather than hash-based fragments by using:

App.Router.reopen({
  location: 'history'
});

But I can find no mention of what will happen if a browser doesn't support the History API. Will it fall back to using a hash like History.js?

If not, should I check for History API support and switch history implementation to hash if it isn't supported?

There doesn't seem to be any History API support detection in the ember source.

So if you set location to history, and there's no support, your routing will probably fail.

If you intend to support old browsers, safest bet is like you said:

if (window.history && window.history.pushState) {
    App.Router.reopen({
      location: 'history'
    });
}

UPDATE 23 Jan 2014

You can now use location:'auto' if you enable ember-routing-auto-location feature in canary.

What about the case where a user puts in a direct url that assumes the history api? – Disused
