Hi Dan I have an issue with the latest changes in zope.publisher.http.py The redirect method in HTTPResponse http.py line: 880 forces a ValueError. Because the Apache HTTP_HOST and the target_host to not compare. def redirect(self, location, status=None, trusted=False): location = str(location) if not trusted: scheme, target_host, path, query, fragment = ( urlparse.urlsplit(location)) if target_host and target_host != self._request.get('HTTP_HOST'): raise ValueError( "Untrusted redirect to host %r not allowed." % target_host) Apache uses <DOMAIN> in HTTP_HOST like expected and the method used with urlparse.urlsplit(location) returns <DOMAIN:PORT> as target_host value. I'm not sure if this is an issue or a bad Apache rewrite configuration. As far as I see we should remove the PORT part from the target_host value. right? I'm not sure if remove the port info from the value if this is contra productive for security. If so what is the correct concept for make the Apache rewrite work? I guess there is no way to support both. btw, I'll run into this problem after a redirect during authentication login form to the cameform url. This should be reproducable by any other apache (port) rewrite setup.
