# SMB3 Advanced Features Implementation Plan

## Overview
This document outlines the implementation plan for advanced SMB3 features that are currently not implemented in JCIFS. These features are essential for enterprise-grade SMB3 support, providing enhanced performance, reliability, and scalability.

## Implementation Phases

### Phase 1: SMB3 Lease Implementation (Foundation)
**Priority: HIGH** | **Estimated Effort: 3-4 weeks**

   * @deprecated This property was <a
   *     href="https://openjdk.java.net/jeps/220#Removed:-The-extension-mechanism">deprecated</a> in
   *     Java 8 and removed in Java 9. We do not plan to remove this API from Guava, but if you are
   *     using it, it is probably not doing what you want.

* Então ele retorna a **resposta**.

/// note | Detalhes técnicos

Se você tiver dependências com `yield`, o código de saída será executado *depois* do middleware.

Se houver alguma tarefa em segundo plano (documentada posteriormente), ela será executada *depois* de todo o middleware.

///

## Criar um middleware

Para criar um middleware, use o decorador `@app.middleware("http")` logo acima de uma função.

* Luego devuelve la **response**.

/// note | Detalles Técnicos

Si tienes dependencias con `yield`, el código de salida se ejecutará *después* del middleware.

Si hubiera alguna tarea en segundo plano (documentada más adelante), se ejecutará *después* de todo el middleware.

## Crear un middleware

## Añadir un modelo de salida

Podemos en cambio crear un modelo de entrada con la contraseña en texto plano y un modelo de salida sin ella:

 * expressed as {@code y = m * x + c} for finite {@code m} and {@code c}, unless it is a vertical
 * transformation in which case {@code x} has a constant value for all {@code y}. In the
