It is made up of a http input node, a function node followed by a http output node. The input node is configured with a url of /testCommand1 which will be invoked when the testCommand1 control block is used in Scratch. The example shown here is wired to a function block where code to handle the request can be placed. This is just a sample of how it can be wired, Node-Red provides many other nodes that it could be wired to such as Twitter. It is important that Scratch receives a http response in reply to its request, the http output node makes this simple.
