About

The interest-based advertising opt-out allowed sites to exclude themselves from Federated Learning of Cohorts (FLoC) cohort calculations using the "interest-cohort=()" permission policy. It is now deprecated and support for it has been removed from Chromium in February 2022.

WebSocket is a communication protocol that enables persistent, full-duplex data exchange between a client and a server over a single TCP connection.

It maintains a long-lived connection that allows low-latency message exchange, supports both text and binary frames, minimizes overhead by avoiding repeated request headers, and enables servers to push data to clients in real time.
