Consider a production Laravel application that needs to use Headers and cookies. How should the developer approach the requirement, and what should be checked before releasing it? Assume the system receives real users, real data and concurrent requests. The correct approach is to identify where headers and cookies belongs, define its inputs and outputs, protect the boundary with validation and authorization where applicable, consider database and performance implications, and add automated tests for the expected behavior. Concept-specific reasoning: Responses can carry headers and cookies when an application needs to control caching, content type or client state. A useful implementation pattern is: return response()->json([ 'message' => 'Created', 'data' => $product ], 201);
