### Détails techniques : `root_path` { #technical-details-root-path }

Lorsque vous montez une sous‑application comme ci‑dessus, FastAPI se charge de communiquer le chemin de montage à la sous‑application au moyen d'un mécanisme de la spécification ASGI appelé `root_path`.

De cette manière, la sous‑application saura utiliser ce préfixe de chemin pour l'interface de documentation.
