Gateway does not inspect or log [WebSocket](https://datatracker.ietf.org/doc/html/rfc6455) traffic. Instead, Gateway will only log the HTTP details used to make the WebSocket connection, as well as [network session information](https://developers.cloudflare.com/logs/reference/log-fields/account/zero_trust_network_sessions/). To filter your WebSocket traffic, create a policy with the `101` HTTP response code.
