classes: informational responses, successful responses, redirects, client errors, and servers errors. Information responses 100 Continue This interim response indicates that everything so far is OK and that the client should continue with the request or ignore it if it is already finished. 101 Switching Protocol This code is sent in response to an Upgrade: request header by the client, and indicates that the protocol the server is switching too. It was introduced to allow migration to an incompatible protocol version, and is not in common use. Successful responses 200 OK The request has succeeded. The meaning of a success varies depending on the HTTP method: GET: The resource has been fetched and is transmitted in the message body. HEAD: The entity headers are in the message body. POST: The resource describing the result of the action is transmitted in the message body. TRACE: The message body contains the request message as received by the server

There are no required headers for this class http status code 0 of status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST http code 302 NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one

or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. Proxies MUST https://developer.mozilla.org/en-US/docs/Web/HTTP/Status forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx This class of status code indicates that the client's request was successfully received, understood, and accepted. 10.2.1 200 OK The request has succeeded.

HTTP status codes are three-digit codes, and are grouped into five different classes. The class of a status code http status can be quickly identified by its first digit: 1xx: Informational 2xx: Success 3xx: Redirection 4xx: Client Error 5xx: Server Error This guide focuses on identifying and troubleshooting the most commonly encountered HTTP error codes, i.e. 4xx and 5xx status codes, from a system administrator's perspective. There are many situations that could cause a web server to respond to a request with a particular error code--we will cover common potential causes and solutions. Client and Server Error Overview Client errors, http status code or HTTP status codes from 400 to 499, are the result of HTTP requests sent by a user client (i.e. a web browser or other HTTP client). Even though these types of errors are client-related, it is often useful to know which error code a user is encountering to determine if the potential issue can be fixed by server configuration. Server errors, or HTTP status codes from 500 to 599, are returned by a web server when it is aware that an error has occurred or is otherwise not able to process the request. General Troubleshooting Tips When using a web browser to test a web server, refresh the browser after making server changes Check server logs for more details about how the server is handling the requests. For example, web servers such as Apache or Nginx produce two files called access.log and error.log that can be scanned for relevant information Keep in mind that HTTP status code definitions are part of a standard that is implemented by the application that is serving requests. This means that the actual status code that is returned depends on how the server software handles a particular error--this guide should generally point you in the right direction Now that you have a high-level understanding of HTTP status codes, we will look at the commonly encountered errors. 400 Bad Request The 400 status code, or Bad Request
422 - Unprocessable Entity Last modified 23:29, 6 Oct 2008 Table of contentsNo headers 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. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.
