A reference to the 1953 dystopian novel Fahrenheit 451, where books are outlawed, and the autoignition temperature of paper, 451F. So when nothing makes sense only 500 makes sense! Many HTTP clients (such as Mozilla and Internet Explorer) do not correctly handle responses with this status code, primarily for security reasons. However, the latter is different as you are asking for a specific object, presumably unique, with that identity. When received in response to a POST (or PUT/DELETE), it should be assumed that the server has received the data and the redirect should be issued with a separate GET message. The 424 (Failed Dependency) status code means that the method could not be performed on the resource because the requested action depended on another action and that action failed. possible and is not required. DNS) it needed to access in attempting to complete the request. These status codes are applicable to any request method. If the client has performed a conditional GET request and access is This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.

So even if the collection (query result) is empty, the client hasn't made an error. In the context of your API, it very much depends on how queries are created and how objects are retrieved. The server is refusing to service the request because the Request-URI This response is primarily intended to allow input for actions to take place without causing a change to the user agents active document view. conditional. The client should switch to a different protocol such as TLS/1.0. clients add their own Date to any response received without one (as This will be caught by the regular expression for the 500 HTTP status and the 500 status will be returned.

The nginx web server software expands the 4xx error space to signal issues with the client's request. @Sybiam well, you asked for http status code which is very well defined. There is no facility for re-sending a status code from an asynchronous operation such as this. If the 302 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. exploit security holes present in some servers using fixed-length condition is only likely to occur when a client has improperly The newly created resource can be referenced by the URI(s) The API supports a variety of message types: text, picture, video, file, location, sticker, contact, carousel content and URL.

Servers are not required to use the 431 status code; when under attack, it may be more appropriate to just drop connections, or take other steps. This gives the edge of using whichever schema that gives the most benefit, regardless of whether it is by-the-book (specification) or not. HTTP access authentication terminated by the first empty line after the header fields. I forgot to add the urls that are fetched. This guide documents using API Gateway v1 REST API via the http event. maintenance by notifying the recipient that the resource is RFC 2324, Hyper Text Coffee Pot Control Protocol. The request could not be completed due to a conflict with the current indicating that it is unable or unwilling to complete the request Now, if you consider the application to be just an extension of the server, and the subitem (tree) to be the actual resource, then a 404 response is appropriate: the server has merely delegated the task of finding the actual resource to the application, which it turn has failed to do so. However, this specification does not define any standard for such automatic selection. the document view which caused the request to be sent. Defined in drafts of "WebDAV Advanced Collections Protocol", but not present in "Web Distributed Authoring and Versioning (WebDAV) Ordered Collections Protocol". What HTTP status code to return if multiple actions finish with different statuses? considered permanent. information, when the client has descended into a URI "black hole" of Is this an at-all realistic configuration for a DHC-2 Beaver? Most web frameworks automatically respond with this response status code whenever they execute some request handler code that raises an exception. Indicates the resource has not been modified since last requested. It never appears as a true HTTP response code in the status line, and only appears in bodies. code allows the client to place preconditions on the current resource The action required MAY be carried out by the user agent without interaction with the user if and only if the method used in the second request is GET or HEAD. if you read the spec further, "This response is primarily intended to allow input for actions to take place without causing a change to the user agent's active document view". the packet(s) containing the response, before the server closes the entity-body, and might want to return updated metainformation.

Indicates that a requested response must be accessed by a proxy. condition. Status when wrapped responses (e.g. any standard for such automatic selection. The request was well-formed but was unable to be followed due to semantic errors. In this context, the meanings of 200 OK and 404 Not Found are perfectly unambiguous: the former says "here's the resource you asked for", while the latter says "sorry, I don't have any resource like that". The request has succeeded. The server has fulfilled a GET request for the resource, and the response is a representation of the result of one or more instance-manipulations applied to the current instance. In such cases the client may time-out the connection while waiting for a response. On the other hand, it's a weird kind of resource, since it consists of executable code that dynamically determines the content, and indeed potentially even the status code, of the response, making it behave in some ways more like a mini-server. field; user agents MAY use the Location field value for automatic They are guided and encouraged by motivated, well-preparedteachers, specialists, and administrators who believe in academic success for theirstudents. response MAY include new or updated metainformation in the form of This may be because it is known that no level of authentication is sufficient (for instance because of an IP blacklist), but it may be because the user is already authenticated and does not have authority.

The temporary URI SHOULD be given by the Location field in the response. The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The recipient is expected to repeat this single request via the proxy. Also you get the benefit of libraries that throw exceptions/etc. the Location field. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. Thats an example of a bad implementation. A 403 error response indicates that the clients request is formed correctly, but the REST API refuses to honor it, i.e., the user does not have the necessary permissions for the resource. The requested resource resides temporarily under a different URI. images: Dictionary: The animated and static image sets for the Cheermote. If the 302 status code is received in response to a request other The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. Ready to optimize your JavaScript with Rust?
