REST Requests
A REST request is associated with an HTTP operation and can use any of the following HTTP operations based on the type of request:
- 
                     GET– Retrieve a resource or a collection of resources
- 
                     POST– Create a new resource
- 
                     PUT– Update a resource
- 
                     DELETE– Delete a resource
Because REST for RAD supports only JSON as the content type, you must include one of the following values in the HTTP header of a REST request:
- 
                     Set the value of the Content-Typefield toapplication/json.
- 
                     Set the value of the Acceptfield to*/*orapplication/json.
