What does the response code 202 and 204 mean?
The HyperText Transfer Protocol (HTTP) 202 Accepted response status code indicates that the request has been accepted for processing, but the processing has not been completed; in fact, processing may not have started yet.
Which HTTP status code is usually returned when a resource was found and returned?
General status code. Most common code used to indicate success. The origin server MUST create the resource before returning the 201 status code. If the action cannot be carried out immediately, the server SHOULD respond with 202 (Accepted) response instead.
How to return additional info with HTTP error status codes?
EnsureSuccessStatusCode will throw the same exception as GetStringAsync in the first sample code. Web services should usually throw exceptions from web method code so that they are returned to the client inside the SOAP response. Still, sometimes the client needs to inspect other HTTP server responses as well.
What does it mean when a HTTP response code is sent?
This interim response indicates that everything so far is OK and that the client should continue the request, or ignore the response if the request is already finished. This code is sent in response to an Upgrade request header from the client, and indicates the protocol the server is switching to.

HTTP protocol defines status codes as the means of informing the client about different error conditions on the server during the request processing. Sometimes it can be beneficial to include additional information about the error that occurred. The protocol allows two different approaches in such cases:
What does unauthenticated mean in the HTTP standard?
Although the HTTP standard specifies “unauthorized”, semantically this response means “unauthenticated”. That is, the client must authenticate itself to get the requested response. This is an experimental API that should not be used in production code. This response code is reserved for future use.
