how do i generate meta http-equiv='refresh' using html helper?
i read in user guide to generate http-equiv='content' you can use 'name'=> 'content', but when i use it for refresh, it doesn't generate http-equiv, the html helper generate name='refresh'... for now i'm using direct typing using echo, but i wish that html helper can generate this meta tag

oops... never mind... i got it... i didn't read the type=>'equiv' at the end of the content-type sample in user guide....
