TCP Fast Open

TCP Fast Open (TFO) is a network feature that speeds up the process of establishing a secure connection between a device and a server. Normally, opening a connection involves a handshake where both parties agree to communicate, which takes a small amount of time. TFO allows data to be sent during this handshake, saving time and reducing delays. This is especially useful for frequent or rapid connections, improving browsing speed and performance without compromising security.
