 * There are trade-offs when selecting which options to include when negotiating a secure connection
 * to a remote host. Newer TLS options are quite useful:
 *
 *  * Server Name Indication (SNI) enables one IP address to negotiate secure connections for

## OAuth2 { #oauth2 }

OAuth2 is a specification that defines several ways to handle authentication and authorization.

It is quite an extensive specification and covers several complex use cases.

It includes ways to authenticate using a "third party".

That's what all the systems with "login with Facebook, Google, X (Twitter), GitHub" use underneath.

    * Um exemplo é `404`, para uma resposta "Não encontrado".
    * Para erros genéricos do cliente, você pode usar apenas `400`.
* `500 - 599` são para erros do servidor. Você quase nunca os usa diretamente. Quando algo der errado em alguma parte do código do seu aplicativo ou servidor, ele retornará automaticamente um desses códigos de status.

En Python, puedes crear Context Managers [creando una clase con dos métodos: `__enter__()` y `__exit__()`](https://docs.python.org/3/reference/datamodel.html#context-managers).

## Pasos Previos Antes de Iniciar { #previous-steps-before-starting }

Hay muchos casos en los que quieres realizar algunos pasos **antes de iniciar** tu aplicación.

Por ejemplo, podrías querer ejecutar **migraciones de base de datos**.

Pero en la mayoría de los casos, querrás realizar estos pasos solo **una vez**.
