twisted location header redirect

Question

From the render_GET method of a Resource in twisted, is it possible to redirect to a different url entirely (hosted elsewhere)

request.redirect(url) doesn't appear to do anything, and neither does twisted.web.util.Redirect

The equivalent in php would be,

header('location:'.$url);

EDIT

this is the code I'm running

from twisted.web import server, resource
from twisted.internet import reactor

class Simple(resource.Resource):
    isLeaf = True
    def render_GET(self, request):
        request.redirect("www.google.com")
        request.finish()

site = server.Site(Simple())
reactor.listenTCP(8080, site)
reactor.run()

Answer 1

I worked it out in the end with help from the other poster, with request.finish(), the redirect including http:// and returning NOT_DONE_YET

from twisted.web import server, resource
from twisted.internet import reactor

class Simple(resource.Resource):
    isLeaf = True
    def render_GET(self, request):
        request.redirect("http://www.google.com")
        request.finish()
        return server.NOT_DONE_YET

site = server.Site(Simple())
reactor.listenTCP(8080, site)
reactor.run()
