method Socket.prototype.setKeepAlive

import { Socket } from "https://dotland.deno.dev/std@0.116.0/node/net.ts";

setKeepAlive(enable: boolean, initialDelay?: number): this

Enable/disable keep-alive functionality, and optionally set the initial delay before the first keepalive probe is sent on an idle socket.

Enable/disable keep-alive functionality, and optionally set the initial delay before the first keepalive probe is sent on an idle socket.

Set initialDelay (in milliseconds) to set the delay between the last data packet received and the first keepalive probe. Setting 0 forinitialDelay will leave the value unchanged from the default (or previous) setting.

Enabling the keep-alive functionality will set the following socket options:

SO_KEEPALIVE=1
TCP_KEEPIDLE=initialDelay
TCP_KEEPCNT=10
TCP_KEEPINTVL=1

Parameters

enable: boolean

optional

initialDelay: number

Returns

this

The socket itself.
