425 Too Early
The HTTP 425 Too Early
client error response status code indicates that the server was unwilling to risk processing a request that might be replayed to avoid potential replay attacks.
If a client has interacted with a server recently, early data (also known as zero round-trip time (0-RTT) data) allows the client to send data to a server in the first round trip of a connection, without waiting for the TLS handshake to complete.
A client that sends a request in early data does not need to include the Early-Data
header.
See Early-Data
for more information.
