[galaxy-dev] Redirecting to a URL and breaking the frameset

Hello, Is there a convenient recipe for redirecting to a URL and breaking the frameset? I have been trying to use trans.response.send_redirect with a variety of URLs, either something as simple as url_for("/") or as complicated as a url_for invocation with lots of arguments, but the resulting content produced for the centre frame is always confined to the centre frame and always includes the top navigation bar. I suppose an alternative query would concern whether it is possible to disable the navigation bar when redirecting within the centre frame, but I actually want to update the user information in the navigation bar.
