I use the following code to determine whether the current URL 
corresponds to one of the listed actions:

the 'url' parameter is the action's  absolute url

=======================
    security.declarePublic('weAreHere')
    def weAreHere(self, url=None):
        """ returns true if the url corresponds to the current URL
            useful for portal actions.
        """

        if url.endswith('/'):
           url = url[:len(url)-1]
        url = string.lstrip(url)

        request_url = self.REQUEST.get('URL')
        if request_url.endswith('/index_html'):
           request_url = request_url[:-11]

        query_string = self.REQUEST.get('QUERY_STRING', None)
        if query_string:
           request_url = request_url + '?' + query_string

        if url == request_url:
           return 1

=======================
