Request processing with middlewares

TYPO3

Description

This skill covers the knowledge of PSR-15 middlewares in TYPO3 - both for frontend and backend request processing.

I know how the core uses middlewares to modularize request processing (middleware dispatcher, chained middlewares, …).
I know how to check which middlewares are configured and in which order they get executed.
I know how to write my own middlewares and add them to the frontend and backend request processing.
I know how to overwrite Core-provided middlewares.
