More on REST

In web applications, REST is typically used over HTTP. REST doesn't need to be tied to any specific protocol. In HTTP REST, we mainly use the GET, POST, PUT, and DELETE methods to change the state of the resources we access. Other HTTP methods, such as OPTIONS, HEAD, CONNECT, and TRACE, can be used for more advanced operations, for example, for caching and debugging purposes. Most servers have disabled advanced methods for security and simplicity reasons; however, you can enable them by adjusting the server configuration files. As JSON is used as a primary media type for major applications, we also use only the JSON media type for our web service calls.
