I have a route defined as below.

$route['manage-vehicles'] = new Zend_Controller_Router_Route(
  'vehicles/manage/page/:page',
  array(
    'controller' => 'vehicles',
    'action'     => 'manage',
    'page'       => '1'
  )
);

When the 'page' parameter is not specifically defined (e.g. in a menu constructed using the navigation component), the resultant URL is

/vehicles/manage/page

I would much prefer or the URL not to to display the default paramater key in this scenario

i.e. /vehicles/manage

Any ideas how to accomplish this would be appreciated?

Thanks.
