Request and response

Now that we have had a quick look at the demo ValuesController, let's examine exactly how the client sends the request and how it receives the response.

A REST request generally consists of the following:

• HTTP verb: This denotes what kind of operation the requests want to perform on the server.
• Header: This element of the REST request allows the client to pass more information about the request.
• URL: The actual path to the resource that the REST request wants to operate on.
• Body: The body can contain extra data related to a resource to identify or update it. This is optional though.
