SMB3 leases provide a client caching mechanism that replaces the traditional oplock mechanism. Leases enable better performance through client-side caching while maintaining cache coherency across multiple clients.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13**: SMB2 CREATE Request with Lease Context
- **MS-SMB2 Section 2.2.14**: SMB2 CREATE Response with Lease State
- **MS-SMB2 Section 2.2.23**: SMB2 LEASE_BREAK Notification

But it provides you the tools to simplify the process as much as possible without compromising flexibility, robustness, or security.

And you can use and implement secure, standard protocols, like OAuth2 in a relatively simple way.

Bezpieczeństwo i uwierzytelnianie jest zintegrowane. Bez żadnych kompromisów z bazami czy modelami danych.

Wszystkie schematy bezpieczeństwa zdefiniowane w OpenAPI, w tym:

* Podstawowy protokół HTTP.
* **OAuth2** (również z **tokenami JWT**). Sprawdź samouczek [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* Klucze API w:
    * Nagłówkach.
    * Parametrach zapytań.

These headers preserve information about the original request that would otherwise be lost:

* **X-Forwarded-For**: The original client's IP address
* **X-Forwarded-Proto**: The original protocol (`https`)
* **X-Forwarded-Host**: The original host (`mysuperapp.com`)

When **FastAPI CLI** is configured with `--forwarded-allow-ips`, it trusts these headers and uses them, for example to generate the correct URLs in redirects.
