zendframework baseUrl view helper in bootstrap

[Xklark]

My website uses the zend framework and runs in a sub folder, for example: http://www.example.com/sub/folder. Now I want to prepend my css links with /sub/folder/ to make the css load in pages like http://www.example.com/sub/folder/product/abc, I thought I found a view helper to do this BaseUrl but BaseUrl seems only to work in actual view files and not in a bootstrap class.Does anybody know the reason for this and an exceptable workaround?This is Snippet of my boodstrap class.\[code\]class Bootstrap extends Zend_Application_Bootstrap_Bootstrap{ protected function _initStylesheet() { $this->_logger->info('Bootstrap ' . __METHOD__); $this->bootstrap('view'); $this->_view = $this->getResource('view'); $this->_view->headLink()->appendStylesheet($this->_view->baseUrl('/css/main.css')); }}\[/code\]
