Middleware Execution Order and Request Processing Pipeline

  1. Request middlewares execute top-to-bottom, response middlewares execute bottom-to-top in reverse order of MIDDLEWARE list

  2. Both request and response middlewares execute in the same top-to-bottom order as defined in MIDDLEWARE

  3. Middleware execution order is determined by priority attribute, not by MIDDLEWARE list order

  4. All middlewares are applied simultaneously to request and response without any specific order

Show answer & explanation

Correct answer

Request middlewares execute top-to-bottom, response middlewares execute bottom-to-top in reverse order of MIDDLEWARE list

Explanation

Django processes middleware in the order defined in MIDDLEWARE setting during request, and in reverse order during response, following a specific pipeline pattern.
