* `minimum_size` - Não comprima respostas menores que este tamanho mínimo em bytes. O padrão é `500`.
* `compresslevel` - Usado durante a compressão GZip. É um inteiro variando de 1 a 9. O padrão é `9`. Um valor menor resulta em uma compressão mais rápida, mas em arquivos maiores, enquanto um valor maior resulta em uma compressão mais lenta, mas em arquivos menores.
