Module websocket 

WebSocket frame handling for frame-level inspection.

This module provides WebSocket frame parsing and encoding per RFC 6455, enabling agents to inspect individual WebSocket frames for security purposes.

Architecture

After a WebSocket upgrade (101 response), Sentinel can optionally intercept the bidirectional byte stream and parse it into frames for inspection:

Client <-> [Frame Parser] <-> Sentinel <-> [Frame Parser] <-> Upstream
                |                                |
                v                                v
         WebSocketFrame                   WebSocketFrame
                         \               /
                          v             v
                       Agent Inspector
                    (Allow/Drop/Close)

Features

• RFC 6455 compliant frame parsing
• Masking/unmasking support (client frames are masked)
• Configurable maximum frame size
• Frame-level agent inspection
