Containers (mainly Linux containers) are a very **lightweight** way to package applications including all their dependencies and necessary files while keeping them isolated from other containers (other applications or components) in the same system.

Help with translations is VERY MUCH appreciated! And it can't be done without the help from the community. 🌎 🚀

Here are the steps to help with translations.

## Forbid Extra Cookies { #forbid-extra-cookies }

In some special use cases (probably not very common), you might want to **restrict** the cookies that you want to receive.

Tudo isso pode parecer abstrato. Não se preocupe. Você verá tudo isso em ação no [Tutorial - Guia do usuário](tutorial/index.md){.internal-link target=_blank}.

O importante é que, usando tipos padrão de Python, em um único local (em vez de adicionar mais classes, decoradores, etc.), o **FastAPI** fará muito trabalho para você.

        // Test with a long message
        String message = "This is a very long error message that describes in detail why the job was not found. "

/// tip

It's very common in Python packages to try the best to **avoid breaking changes** in **new versions**, but it's better to be safe, and install newer versions intentionally and when you can run the tests to check everything is working correctly.

    * As we said above, only one process can be listening on a specific IP and port.
    * This is one of the reasons why it's very useful when the same TLS Termination Proxy also takes care of the certificate renewal process.
