can www.example.com/...#!... always use controller=redirect

In Ruby on Rails routing (using route.rb), can it say, for any URL
having the form:

    www.example.com/ ... #! ...

then use controller `redirect` ?

This is so that in AJAX, some page can tag the `#!` at the end of URL so
that the real content of interest is the part after the `#!`

Site_url = www.example.com
redirected_to #{site_url}

or directly in routes.rb can work a bit you have to google
