Configure exceptions
When an exception occurs, there are specific status codes and messages that are returned. For example, when the requested item is not found, the error returned is 404.
You can control the behavior of the error response mechanism by setting the IncludeErrorDetailPolicy property of the HttpConfiguration object.
EXAMPLE: To return the call stack of the exceptions only for local calls, use the following code:
GlobalConfiguration.Configuration.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.LocalOnly
For more information, see MSDN HttpConfiguration.IncludeErrorDetailPolicy Property.
All exception that occur are logged in the Error.log file.
