30:  * The request could not be completed due to a conflict with the current state 
31:  * of the target resource. This code is used in situations where the user might 
32:  * be able to resolve the conflict and resubmit the request.
33:  * 
34:  * The server SHOULD generate a payload that includes enough information for a 
35:  * user to recognize the source of the conflict.
36:  * 
37:  * Conflicts are most likely to occur in response to a PUT request. For example, 
38:  * if versioning were being used and the representation being PUT included 
39:  * changes to a resource that conflict with those made by an earlier 
40:  * (third-party) request, the origin server might use a 409 response to indicate 
41:  * that it can't complete the request. In this case, the response representation 
42:  * would likely contain information useful for merging the differences based on 
43:  * the revision history.
