Code

HTTP Status Code 417 refers to Expectation Failed. This status code indicates that the server cannot meet the requirements of the Expect request-header field sent by the client. When a client sends a request with this header, it is essentially asking the server if it can fulfill certain expectations for the response.

HTTP Status Code 416 refers to Range Not Satisfiable. This status code indicates that the server cannot fulfill a range request made by the client because the specified range is not valid or exceeds the size of the resource.

HTTP Status Code 415 indicates Unsupported Media Type. This status is returned when the server refuses to accept the request because the payload format is in a format that is not supported by the server for the requested resource. For instance, if a client attempts to upload a file with a media type that the server cannot process, such as sending a JSON payload to an endpoint that only accepts XML, the server will respond with this status code.

HTTP Status Code 414 signifies URI Too Long. This status is returned when the server refuses to process a request because the length of the URI exceeds the server's limit. A client might encounter this response when the request includes a long query string or overly long URL, which can happen during complex searches or when sending large amounts of data in the URL. In response, clients should consider shortening the URI, possibly by using POST instead of GET to send data in the body rather than the URL.

HTTP Status Code 413 indicates Payload Too Large. This status is returned when the server refuses to process a request because the request payload is larger than the server is willing or able to process. Essentially, it informs the client that the submitted data exceeds the size limits set by the server, which may be due to server configuration or resource constraints. Clients receiving this response should consider reducing the size of the request payload before retrying.

HTTP Status Code 412 signifies Precondition Failed. This status is returned when a client makes a request that includes certain conditions in the If-Match, If-None-Match, If-Modified-Since, or If-Unmodified-Since headers, but those conditions are not met by the server. Essentially, the server is informing the client that the request cannot proceed because the specified conditions regarding the resource's state are not satisfied.

HTTP Status Code 411 indicates Length Required. This status is returned when the server refuses to accept a request without a defined Content-Length header. When a client sends a request that requires a body, like a POST or PUT, the server expects the client to specify the size of that body. If the client fails to include the Content-Length header, the server will respond with a 411 status, signaling that the request cannot be processed until the required information is provided.

HTTP Status Code 410 signifies Gone. This status is returned when a requested resource is no longer available on the server and there is no forwarding address. Unlike a 404 error, which indicates that the resource might be available again in the future, a 410 status means that the resource has been intentionally removed and is considered permanent.

HTTP Status Code 409 indicates a Conflict. This status is returned when a request cannot be completed due to a conflict with the current state of the resource. For example, this may occur when trying to upload a file that conflicts with an existing one, or if a versioning system detects that the resource has changed since it was last accessed. Essentially, it signals that the request could not be processed because it conflicts with another request or the current resource state, and the client may need to resolve the conflict before resending the request.

HTTP Status Code 408 means Request Timeout. This status is returned when the server did not receive a complete request from the client within the time it was prepared to wait. It indicates that the client’s connection to the server was lost or that the server waited too long for the client to send the request. This could occur due to slow network conditions or an unresponsive client. In essence, the server is signaling that it has timed out waiting for the client to send the necessary data to complete the request.
