Angularjs: Hashbang and HTML5 Modes

$location service has 2 configuration modes which control the format of the URL in the browser address bar:

1. Hashbang mode (the default)
2. HTML5 mode which is based on using the HTML5 History API.

Applications use the same API in both modes and the $location service will work with appropriate URL segments and browser APIs to facilitate the browser URL change and history management.
