Microsoft Silverlight (RIP) only exposed 200 and 404 status codes to the application when using the browser's HTTP stack, presumably due to some API limitation somewhere along the line. See the Remarks section: https://msdn.microsoft.com/en-us/library/system.net.httpstatuscode%28v=vs.95%29.aspx?f=255&MSPPError=-2147217396 https://msdn.microsoft.com/en-us/library/system.net.httpstat... Other client plugins may have similar issues.
