If an incoming request does not validate correctly then a `400` response will be sent.

## `GZipMiddleware` { #gzipmiddleware }

Handles GZip responses for any request that includes `"gzip"` in the `Accept-Encoding` header.

The middleware will handle both standard and streaming responses.

/// note | Detalhes Técnicos

Você pode também pode usar `from starlette.responses import HTMLResponse`.

**FastAPI** providencia o mesmo `starlette.responses` que `fastapi.responses` apenas como uma conveniência para você, o desenvolvedor. Mas a maioria das respostas disponíveis vem diretamente do Starlette.
