شما می‌توانید کدی را برای اجرا با `درخواست`، قبل از اینکه هر *path operation* آن را دریافت کند، اضافه کنید.

همچنین پس از تولید `پاسخ`، قبل از بازگشت آن، می‌توانید کدی را اضافه کنید.

به عنوان مثال، می‌توانید یک هدر سفارشی به نام `X-Process-Time` که شامل زمان پردازش درخواست و تولید پاسخ به صورت ثانیه است، اضافه کنید.
