Detailed breakdown:
1xx (provisional response)
Status codes that indicate a provisional response and require the requester to proceed with the action.
Code Description
100 (Continue) The requester should proceed with the request. The server returns this code to indicate that the first part of the request has been received and is waiting for the rest.
101 (Switch protocol) The requester has asked the server to switch protocols, the server has confirmed and is ready to switch.
2xx (success)
Status code indicating that the request was processed successfully.
Code Description
200 (Success) The server has successfully processed the request. Typically, this means that the server served the requested web page.
201 (Created) The request was successful and the server created a new resource.
202 (Accepted) The server has accepted the request but has not yet processed it.
203 (Unauthorized Information) The server successfully processed the request, but the returned information may have come from another source.
204 (No Content) The server successfully processed the request but returned no content.
205 (Content reset) The server successfully processed the request but returned no content.
206 (Partial Content) The server successfully processed a partial GET request.
3xx (redirect)
indicates that further action is required to complete the request. Typically, these status codes are used for redirection.
code description
300 (multiple choice) The server can perform various actions on the request. The server may select an action based on the requestor (user agent), or provide a list of actions for the requester to choose from.
301 (Moved Permanently) The requested web page has been permanently moved to a new location. When the server returns this response (to a GET or HEAD request), it automatically redirects the requester to the new location.
302 (Moved temporarily) The server is currently responding to the request from a web page in a different location, but the requester should continue to use the original location for future requests.
303 (See other locations) The server returns this code when the requester should use separate GET requests for different locations to retrieve the response.
304 (Not Modified) The requested page has not been modified since the last request. When the server returns this response, no web page content is returned.
305 (Use Proxy) The requester can only use a proxy to access the requested web page. If the server returns this response, it also indicates that the requester should use a proxy.
307 (Temporary Redirect) The server is currently responding to the request from a web page in a different location, but the requester should continue to use the original location for future requests.
4xx (Request Error)
These status codes indicate that the request may have gone wrong, preventing the server from processing it.
Code Description
400 (Bad Request) The server does not understand the syntax of the request.

412 (Precondition not met) The server did not satisfy one of the preconditions set by the requester in the request.
