Understanding the Request Lifecycle
A request passes through several layers before the final UI or API response is returned. Depending on the application and deployment platform, this can involve edge infrastructure, middleware or proxy logic, routing, server rendering, data access, and caching.
Understanding this lifecycle helps explain why a redirect may happen before a page executes or why a response can be cached even though the page contains server code.

Key Takeaways
- A request can pass through multiple infrastructure layers.
- Caching and routing decisions can happen before rendering.
- Understanding the lifecycle makes debugging easier.
