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.

Answer 1

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)

Answer 2

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.
