## Features

### Protocol Support
The library supports a full range of SMB protocols with automatic negotiation:

**Supported Protocols:**
- **SMB1/CIFS**: Legacy support via `jcifs.smb1/` package
- **SMB 2.0.2**: Windows Vista+ (0x0202)
- **SMB 2.1**: Windows 7/Server 2008R2 (0x0210)

    val url: HttpUrl = mockWebServer.url("")
    mockWebServer.bodyLimit = 0L
    mockWebServer.protocolNegotiationEnabled = false
    mockWebServer.protocols = listOf()
    val protocols: List<Protocol> = mockWebServer.protocols
    mockWebServer.useHttps(SSLSocketFactory.getDefault() as SSLSocketFactory, false)
    mockWebServer.noClientAuth()
    mockWebServer.requestClientAuth()
