This method is generally not needed, and only used to force the subsequent call to [method connect_to_host] to use the specified [param host] and [param port] as source address. This can be desired in some NAT punchthrough techniques, or when forcing the source network interface.

If [param enabled] is [code]true[/code], packets will be sent immediately. If [param enabled] is [code]false[/code] (the default), packet transfers will be delayed and combined using [url=https://en.wikipedia.org/wiki/Nagle%27s_algorithm]Nagle's algorithm[/url].

[b]Note:[/b] It's recommended to leave this disabled for applications that send large packets or need to transfer a lot of data, as enabling this can decrease the total available bandwidth.
