keepAlive (property)

When True, KEEPALIVE packets are enabled (for long connections).

- (BOOL)keepAlive

- (void)setKeepAlive:(BOOL)newKeepAlive

Default Value

FALSE

Remarks

This property enables the SO_KEEPALIVE option on the incoming connections. This option prevents long connections from timing out in case of inactivity.

Please note that system TCP/IP stack implementations are not required to support SO_KEEPALIVE.

This property is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.
