Use imperative mood consistently for the first sentence describing an option. "Set this" instead "tell curl to set" or "this sets..." Plus some extra cleanups and rephrasing. Closes #13106

# `--keepalive-time`
|
|
|
|
Set the time a connection needs to remain idle before sending keepalive probes
|
|
and the time between individual keepalive probes. It is currently effective on
|
|
operating systems offering the `TCP_KEEPIDLE` and `TCP_KEEPINTVL` socket
|
|
options (meaning Linux, recent AIX, HP-UX and more). Keepalive is used by the
|
|
TCP stack to detect broken networks on idle connections. The number of missed
|
|
keepalive probes before declaring the connection down is OS dependent and is
|
|
commonly 9 or 10. This option has no effect if --no-keepalive is used.
|
|
|
|
If unspecified, the option defaults to 60 seconds.
