\api\session\kick

I understand /api/session/advance and api\restart but how do you use api/session/kick?

Code:

name: "api/session/kick",
[LIST]
description: "Kick and optionally temporary-ban specified session member",
access: "admin",
responsetype: "json",
parameters: [
{
name: "refid",
type: "int",
optional: false,
description: "RefId of the member to kick"
},
{
name: "ban",
type: "int",
optional: true,
description: "Time of temporary ban from the server, in seconds"
}
],
response: [ ]

[/LIST]
