301 redirects in Grails

Question

I'm currently doing my Grails 301 URL-redirects using the following quite cumbersome "servlet style" method:

def action = {
  ...
  if (shouldRedirect) {
    response.status = 301
    response.setHeader("Location", "http://url/to/redirect/to.html")
    render("")
    return false
  }
  ...
}

Is there any cleaner and more compact Groovy/Grails'y way to perform a 301 redirect?

Please note that I'm talking about 301 redirect, not the standard 302 redirects which can be achieved using the standard Grails redirect(...) mechanism.

Yes, it's now possible to use redirect and specify the permanent parameter as true as described here. For example:

redirect(url: "http://url/to/redirect/to.html", permanent: true)

Is it better to set all controller's redirects to status 301, as far as SEO is concerned, or should one leave them as 302 ? – Alexandre Bourlier Apr 17 '12 at 15:33
@Euoliix If a redirect is really permanent, then you should use 301. If Google sees 302 then supposedly it will check the URL again later. – Ken Liu May 08 '13 at 19:53

The redirect mechanism in Grails currently supports a permanent parameter:

permanent (optional) - If true the redirect will be issued with a 301 HTTP status code (permanently moved), otherwise a 302 HTTP status code will be issued

This should adequately solve your problem, and in a very Grails-y way.
