I want all the production data for my web-app to also flow through my testing environment. Essentially, I want to forward every http request for the production site to the test site (and also have the production website serve it!).
What is a good way to do this? My site is built with Django, and served by mod_wsgi. Is this best implemented at the app-level (Django), web server level (Apache), or the mod_wsgi-level?
