I have a PageTag which shows all the Pages matching a Tag Name passed in the url.

where tags is the pagename
http:://<website>/tags/<slug> it shows the Pages related to the tag
http:://<website>/tags/SearchForm it should redirect to the searchform page

I want to exclude the SearchForm from the slug. Because there is already a action with that name.

class PageTag_Controller extends Page_Controller
{
	static $allowed_actions = array(
		'index',
		'specificTags',
	);
	public static $url_handlers = array(
		'$Slug!' => 'specificTags',
		'' => 'index'
	);
        function index() {	

		$data = array(
			'Results' => array()
		);			
		return $this->->renderWith('PageTag');
        }
	//UrlHandelres not redirecting Hence using common methods to all
	//Controller

	function specificTags() {
                $Slug = $this->request->param('Slug');
		$Tag = Tag::get()->filter('slug',$Slug)->first(); 

		if($Tag) {
			if($Slug == 'SearchForm'){
                             $this->owner->redirect('SearchForm')
                        }

                      return $this->renderWith('PageTag');
       }
}

How do I exclude the SearchFrom from the Url handlers directing to the function specificTags?

Above code still works but I need to include condition in the specificTags function to check whether slug is SearchFrom otherwise it will not work.

Page_Controller::add_extension('ExtensibleSearchExtension');
class ExtensibleSearchExtension extends Extension {

	function SearchForm() {
        }

 	public function results() {
        }
}
