ok i see, but maybe im explaining it wrong
what i want is this:
when someone type something INSIDE THE IFRAME, for exampel here i typed cgtalk.com
i want the text_url copy exactly what the user typed and if it match an listed url, THEN he is directly redirected to google.com
your example works i get the redirecton if y type the url inside the text_url on top and if i hit the go buton.
