To serialize access, protect the data with channel operations or other synchronization primitives

Si una request entrante no se valida correctamente, se enviará un response `400`.

## `GZipMiddleware`

Maneja responses GZip para cualquier request que incluya `"gzip"` en el header `Accept-Encoding`.

El middleware manejará tanto responses estándar como en streaming.
