Laravel: Prevent Sessions for Routes via a Filter

I needed to prevent Laravel from using sessions for a few API endpoints in an app, this is how I did it:

Route::filter('session.remove', function()
    return Config::set('session.driver', 'array');

This can be used quite easily with a route or route group:

    "prefix" => "api/v1",
    "before" => array("session.remove")
), function() {
    Route::get('/search', 'SearchController@getPerformSearch');
