HttpStatusCode

 HTTP (Hypertext Transfer Protocol) response status codes are three-digit numbers returned by a server in response to a client's request made to the server. These codes provide information about the status of the requested resource or about the server's processing of the request. Here are some common HTTP response status codes, grouped by their general categories:

Informational responses (100-199):

100 Continue: The client should continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not been rejected.

101 Switching Protocols: The server is indicating a change in protocol. The client should switch to a different protocol if it wishes to continue the request.

102 Processing: The server is still processing the request. This code is typically used in WebDAV (Web Distributed Authoring and Versioning) scenarios.

103 Early Hints: This status code is primarily intended to be used with the "Link" header to allow the user agent to start preloading resources while the server is still preparing a response.

Successful responses (200-299):

200 OK: The request was successful, and the server returns the requested data in the response body.

201 Created: The request was successful, and a new resource was created on the server. The URI for the newly created resource is provided in the response header.

202 Accepted: The request has been accepted but has not been fully processed. It may be used to acknowledge asynchronous processing.

204 No Content: The server successfully processed the request but there is no additional content to send in the response. Useful for indicating success without returning a response body.

206 Partial Content: The server is delivering only a part of the resource due to a range header sent by the client.

Redirection messages (300-399):

300 Multiple Choices: The requested resource has multiple representations, and the user or client can choose among them.

301 Moved Permanently: The requested resource has been permanently moved to a different location. The client should update its bookmark or link.

302 Found (or Moved Temporarily): Similar to 301, but indicates a temporary redirection.

304 Not Modified: The client's cached copy is up-to-date, and there is no need to transfer the requested resource again.

Client error responses (400-499):

400 Bad Request: The server cannot process the request due to a client error, such as malformed syntax or invalid request message framing.

401 Unauthorized: The request requires user authentication, and the client needs to provide valid credentials.

403 Forbidden: The server understood the request but refuses to authorize it.

404 Not Found: The requested resource could not be found on the server.

Server error responses (500-599):

500 Internal Server Error: A generic error message indicating a problem at the server.

501 Not Implemented: The server does not support the functionality required to fulfill the request.

503 Service Unavailable: The server is temporarily unable to handle the request, usually due to maintenance or overloading.

504 Gateway Timeout: The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server or some other auxiliary server it needed to access in order to complete the request.
