For phoenix eats out I had to do an internal redirect with CherryPy based on the URL that was coming in, but only for the index page. I did it for all other cases in Apache, but decided with the index page to do it using Turbogears.

The main issue, which took me a while to workout, was that I was running CherryPy as a server locally on my dev machine, but in production I am using mod_proxy with apache. CherryPy gives you quick and easy access to the request headers as a dict, so it is easy to punch out and see what is going on. In my dev environment I set up phoenixeatsout.com in my /etc/hosts to resolve to localhost and wrote:

 if cherrypy.request.headers.get("Host") == 'www.phoenixeatsout.com':
    raise cherrypy.InternalRedirect('/restaurants/')

Which worked fine when I was running CherryPy as the http server. With mod_proxy that doesn't work as the host is always localhost:8000 or whatever host and port you are running CherryPy on that Apache connects to through mod_proxy. After pumping out the headers to the main page I changed it in production to:

reqHost = cherrypy.request.headers.get("X-Forwarded-Host")
if reqHost == 'www.phoenixeatsout.com':
    raise cherrypy.InternalRedirect('/restaurants/')

Because it is an internal redirect it slides to that controller without changing the URL to the user's eye. Quite neat.

More And fwiw the point versioning of the South Sea Republic, Cam Riley and Phoenix Eats Out codebase has gone from 1.3.64 to 1.4.0.
