* Décompresser des corps de requête compressés en gzip.
* Journaliser automatiquement tous les corps de requête.

## Gérer les encodages personnalisés du corps de la requête { #handling-custom-request-body-encodings }

Voyons comment utiliser une sous-classe personnalisée de `Request` pour décompresser des requêtes gzip.

///

First, we create a `GzipRequest` class, which will overwrite the `Request.body()` method to decompress the body in the presence of an appropriate header.

If there's no `gzip` in the header, it will not try to decompress the body.

That way, the same route class can handle gzip compressed or uncompressed requests.
