+SPDX-License-Identifier: curl
+Long: no-keepalive
+Help: Disable TCP keepalive on the connection
+Category: connection
+Example: --no-keepalive $URL
+Added: 7.18.0
+See-also: keepalive-time
+Multi: boolean
+---
+Disables the use of keepalive messages on the TCP connection. curl otherwise
+enables them by default.
+
+Note that this is the negated option name documented. You can thus use
+--keepalive to enforce keepalive.
