What is a WebSocket proxy?

A WebSocket proxy is a server that acts as an intermediary between WebSocket clients and WebSocket servers. WebSocket is a protocol that enables bi-directional communication between a client and a server. A WebSocket proxy can be used to optimize the connection between the client and the server, implement security features, enable load balancing and scalability, and provide other advanced features.

The WebSocket proxy is typically deployed as part of a reverse proxy server that distributes WebSocket traffic across multiple servers for increased scalability. The proxy can also serve as an interface between the WebSocket client and the server to optimize the connection and make it more secure, for example by encrypting the connection or improving transmission speed.

Overall, using a WebSocket proxy enables more efficient and secure communication between WebSocket clients and servers, especially in environments with high data volumes or high availability and scalability requirements.
