Is it possible to redirect to different domain retaining the trailing endpoint, from a route?

Question

Is it possible to redirect to a different domain while retaining the trailing endpoint to the other domain. For example, if I hit http://www.example.com/api/:endpoint, I would like to be redirected to http://www.other.com/api/:endpoint. I realise I could probably do this in the route handler, but ideally I would to put it in it in the routes, from www.example.com like so.

RedirectRoute(r'/api/<uri:.*>', redirect_to='http://www.other.com/api/:uri')

I haven't found anything in the documentation, or from a quick browse of the source for webapp2_extras.route that indicates how to deal with this.

So basically my question is, can I do this from the route declaration (or whatever it's referred to), without having to build out an entire route handler?

Answer 1

The documentation for webapp2_extras.routes.RedirectRoute states that the redirect_to argument can either be a string or a callable. A callable will be passed (handler, *args, **kwargs), which you could use to reconstruct a URL using an alternate domain. It doesn't look like you can simply define a string template to do this, however, so you may be stuck writing your own custom Route class.
