The Ember router has four options to manage your application's URL:  `history`,
which uses the HTML5 History API; `hash`, which uses anchor-based URLs; `auto`,
which uses `history` if supported by the user's browser, and falls back to
`hash` otherwise; and `none`, which doesn't update the URL. By default, Ember
CLI configures the router to use `auto`. You can change this option in
`config/environment.js` under `ENV.locationType`.

## history

When using `history`, Ember uses the browser's
[history](http://caniuse.com/history) API to produce URLs with a structure like
`/posts/new`.

Given the following router, entering `/posts/new` will take you to the `posts.new`
route.

```app/router.js
Router.map(function() {
  this.route('posts', function() {
    this.route('new');
  });
});
```

Keep in mind that your server must serve the Ember app from all the URLs defined in your
`Router.map` function. In other words, if your user directly navigates to
`/posts/new`, your server must be configured to serve your Ember app in
response.

## hash

The `hash` option uses the URL's anchor to load the starting state of your
application and will keep it in sync as you move around. At present, this relies
on a [hashchange](http://caniuse.com/hashchange) event existing in the browser.

In the router example above, entering `/#/posts/new` will take you to the `posts.new`
route.

## none

Finally, if you don't want the browser's URL to interact with your application
at all, you can disable the location API entirely by setting `ENV.locationType`
to `none`. This is useful for
testing, or when you don't want Ember to muck with the URL (for example when you embed your
application in a larger page).
