How does TCP KeepAlive work?
When two hosts are connected over a network via TCP/IP, TCP Keepalive Packets can be used to determine if the connection is still valid, and terminate it if needed. Typically TCP Keepalives are sent every 45 or 60 seconds on an idle TCP connection, and the connection is dropped after 3 sequential ACKs are missed.
Why is it important to close a persistent connection?
Persistent connections provide a mechanism by which a client and a server can signal the close of a TCP connection. This signaling takes place using the Connection header field (section 14.10). Once a close has been signaled, the client MUST NOT send any more requests on that connection.
Why Keep-Alive is needed?
The Benefits of Connection Keep Alive The HTTP keep-alive header maintains a connection between a client and your server, reducing the time needed to serve files. A persistent connection also reduces the number of TCP and SSL/TLS connection requests, leading to a drop in round trip time (RTT).
