Persistent Connection

  • refers to a long-lived connection between a client and a server that remains open for an extended period, allowing multiple requests and responses to be sent without establishing a new connection for each interaction

  • Typically occurs in websockets

  • keeping the connection open for an extended duration, persistent connections offer several advantages.

    • They eliminate the need to establish a new connection for each request, reducing the overhead associated with repeated handshakes.

    • This approach also enables real-time and interactive communication between the client and server, making it well-suited for applications that require instant updates and bidirectional data transfer.

  • Can occur via http

    • keep-alive connections, where the server keeps the TCP connection open for multiple HTTP requests and responses within a certain timeframe.
