The document discusses implementing a multi-tier architecture in Django. It describes using a single Django proxy server that can select templates, database connections, and URL resolvers at runtime based on the request. Key points covered include using middleware, thread locals, template loaders, database routers, and the django.db.connections module to enable runtime selection of these components. The document also stresses that the entire rendering pipeline must be configurable on a per-request basis and cautions that caching without a cache manager can cause issues.

- 8. LESSONS LEARNED ïŹ Caching without a CacheManager is Evil. def value(self): if not has_attr(self, _value): self._value = self.compute_value() return self._value ïŹ The Entire Rendering Pipeline must be Configurable on a Request. ïŹ (not talked here) Class Views and Mixins are amazingly flexible.
