This is possible with bleeding-edge angular.js (tested with git master 4ae46814ff).
You can use request http interceptor. Like this.
angular.module('yourapp')
.factory('timeoutHttpIntercept', function ($rootScope, $q) {
return {
'request': function(config) {
config.timeout = 10000;
return config;
}
};
});
And then in .config inject $httpProvider and do this:
$httpProvider.interceptors.push('timeoutHttpIntercept');
