Example usage

public byte[] HandleRESTRequest(string Capabilities, string resourceName, string operationName, string operationInput, string outputFormat, string requestProperties, out string responseProperties)
{
     // ArcGIS 10.1 bug workaround.
     GetActualFormat(operationInput, ref outputFormat);
     return _reqHandler.HandleRESTRequest(Capabilities, resourceName, operationName, operationInput, outputFormat, requestProperties, out responseProperties);
}

You da man! Thanks!
