Error incorrect data to updating code 306

If the request body is large, sending it to a server when a request has already been rejected based upon inappropriate headers is inefficient.To have a server check if the request could be accepted based on the request's headers alone, a client must send Expect: 100-continue as a header in its initial request and check if a 100 Continue status code is received in response before continuing (or receive 417 Expectation Failed and not continue).Methods can potentially take a long period of time to process, especially methods that support the Depth header.
There are no required headers for this class of status code.
This class of status code indicates that the client's request was successfully received, understood, and accepted.
