Fields

Name	Value	Description
Success	0	No error was encountered.
NameResolutionFailure	1	The name resolver service could not resolve the host name.
ConnectFailure	2	The remote service point could not be contacted at the transport level.
ReceiveFailure	3	A complete response was not received from the remote server.
SendFailure	4	A complete request could not be sent to the remote server.
PipelineFailure	5	The request was a pipelined request and the connection was closed before the response was received.
RequestCanceled	6	The request was canceled, the Abort() method was called, or an unclassifiable error occurred. This is the default value for Status.
ProtocolError	7	The response received from the server was complete but indicated a protocol-level error. For example, an HTTP protocol error such as 401 Access Denied would use this status.
ConnectionClosed	8	The connection was prematurely closed.
TrustFailure	9	A server certificate could not be validated.
SecureChannelFailure	10	An error occurred while establishing a connection using SSL.
ServerProtocolViolation	11	The server response was not a valid HTTP response.
KeepAliveFailure	12	The connection for a request that specifies the Keep-alive header was closed unexpectedly.
Pending	13	An internal asynchronous request is pending.
Timeout	14	No response was received during the time-out period for a request.
ProxyNameResolutionFailure	15	The name resolver service could not resolve the proxy host name.
UnknownError	16	An exception of unknown type has occurred.
MessageLengthLimitExceeded	17	A message was received that exceeded the specified limit when sending a request or receiving a response from the server.
CacheEntryNotFound	18	The specified cache entry was not found.
RequestProhibitedByCachePolicy	19	The request was not permitted by the cache policy. In general, this occurs when a request is not cacheable and the effective policy prohibits sending the request to the server. You might receive this status if a request method implies the presence of a request body, a request method requires direct interaction with the server, or a request contains a conditional header.
RequestProhibitedByProxy	20	This request was not permitted by the proxy.
