angular location

// Hashbang for SEO
angular.module('awesomeModule')
.config(['$locationProvider',
    function($locationProvider) {
        $locationProvider.hashPrefix("!");
    }

Just a clarification # is the default
$locationProvider.hashPrefix("!");
add a ! the # the default so make #!

This url type
http://mgcrea.github.io/angular-strap/##scrollspy
are set with
$locationProvider.hashPrefix("#");

• is the default, angular need at least # to identify deep linking part of the url

• #! is the recommanded pattern named "hash bang"
  To configure it this line is necessary in the above code $locationProvider.hashPrefix("!");
