* Decompressing gzip-compressed request bodies.
* Automatically logging all request bodies.

## Conclusão { #conclusion }

Com isso, você deve ter uma compreensão básica do que são **variáveis ​​de ambiente** e como usá-las em Python.

Você também pode ler mais sobre elas na <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia para Variáveis ​​de Ambiente</a>.

## Additional Features { #additional-features }

There are some extra features to handle security apart from the ones covered in the [Tutorial - User Guide: Security](../../tutorial/security/index.md){.internal-link target=_blank}.

/// tip

The next sections are **not necessarily "advanced"**.
