The following is a list of HyperText Transfer Protocol (HTTP) response status codes. This includes codes from IETF internet standards as well as unstandardised RFCs, other specifications and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; the bare minimum for an HTTP client is that it recognises these five classes. Microsoft IIS may use additional decimal sub-codes to provide more specific information,[1] but these are not listed here. The phrases used are the standard examples, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard.

[edit]1xx Informational

Request received, continuing process.[2]

This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions.

100 Continue
This means that the server has received the request headers, and that the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). If the request body is large, sending it to a server when a request has already been rejected based upon inappropriate headers is inefficient. To have a server check if the request could be accepted based on the request's headers alone, a client must send Expect: 100-continue as a header in its initial request[2] and check if a 100 Continue status code is received in response before continuing (or receive 417 Expectation Failed and not continue).[2]
101 Switching Protocols
This means the requester has asked the server to switch protocols and the server is acknowledging that it will do so.[2]
102 Processing (WebDAV) (RFC 2518)
As a WebDAV request may contain many sub-requests involving file operations, it may take a long time to complete the request. This code indicates that the server has received and is processing the request, but no response is available yet.[3] This prevents the client from timing out and assuming the request was lost.
103 Checkpoint
This code is used in the Resumable HTTP Requests Proposal to resume aborted PUT or POST requests.[4]
122 Request-URI too long
This is a non-standard IE7-only code which means the URI is longer than a maximum of 2083 characters.[5][6] (See code 414.)

[edit]2xx Success

This class of status codes indicates the action requested by the client was received, understood, accepted and processed successfully.

200 OK
Standard response for successful HTTP requests. The actual response will depend on the request method used. In a GET request, the response will contain an entity corresponding to the requested resource. In a POST request the response will contain an entity describing or containing the result of the action.[2]
201 Created
The request has been fulfilled and resulted in a new resource being created.[2]
202 Accepted
The request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place.[2]
203 Non-Authoritative Information (since HTTP/1.1)
The server successfully processed the request, but is returning information that may be from another source.[2]
204 No Content
The server successfully processed the request, but is not returning any content.[2]
205 Reset Content
The server successfully processed the request, but is not returning any content. Unlike a 204 response, this response requires that the requester reset the document view.[2]
206 Partial Content
The server is delivering only part of the resource due to a range header sent by the client. The range header is used by tools like wget to enable resuming of interrupted downloads, or split a download into multiple simultaneous streams.[2]
207 Multi-Status (WebDAV) (RFC 4918)
The message body that follows is an XML message and can contain a number of separate response codes, depending on how many sub-requests were made.[7]
208 Already Reported (WebDAV) (RFC 5842)
The members of a DAV binding have already been enumerated in a previous reply to this request, and are not being included again.
226 IM Used (RFC 3229)
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. [8]

[edit]3xx Redirection

The client must take additional action to complete the request.[2]

This class of status code indicates that further action needs to be taken by the user agent in order to fulfil the request. 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. A user agent should not automatically redirect a request more than five times, since such redirections usually indicate an infinite loop.

300 Multiple Choices
Indicates multiple options for the resource that the client may follow. It, for instance, could be used to present different format options for video, list files with differentextensions, or word sense disambiguation.[2]
301 Moved Permanently
This and all future requests should be directed to the given URI.[2]
302 Found
This is an example of industrial practice contradicting the standard.[2] HTTP/1.0 specification (RFC 1945) required the client to perform a temporary redirect (the original describing phrase was "Moved Temporarily"),[9] but popular browsers implemented 302 with the functionality of a 303 See Other. Therefore, HTTP/1.1 added status codes 303 and 307 to distinguish between the two behaviours.[10] However, some Web applications and frameworks use the 302 status code as if it were the 303.[citation needed]
303 See Other (since HTTP/1.1)
The response to the request can be found under another URI using a GET method. 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.[2]
304 Not Modified
Indicates the resource has not been modified since last requested.[2] Typically, the HTTP client provides a header like the If-Modified-Since header to provide a time against which to compare. Using this saves bandwidth and reprocessing on both the server and client, as only the header data must be sent and received in comparison to the entirety of the page being re-processed by the server, then sent again using more bandwidth of the server and client.
305 Use Proxy (since HTTP/1.1)
Many HTTP clients (such as Mozilla[11] and Internet Explorer) do not correctly handle responses with this status code, primarily for security reasons.[2]
306 Switch Proxy
No longer used.[2] Originally meant "Subsequent requests should use the specified proxy."[12]
307 Temporary Redirect (since HTTP/1.1)
In this occasion, the request should be repeated with another URI, but future requests can still use the original URI.[2] In contrast to 303, the request method should not be changed when reissuing the original request. For instance, a POST request must be repeated using another POST request.
308 Resume Incomplete
This code is used in the Resumable HTTP Requests Proposal to resume aborted PUT or POST requests.[4]

[edit]4xx Client Error

The 4xx class of status code is intended for cases in which the client seems to have erred. Except when responding to a HEAD request, the server should include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition. These status codes are applicable to any request method. User agentsshould display any included entity to the user.

400 Bad Request
The request cannot be fulfilled due to bad syntax.[2]
401 Unauthorized
Similar to 403 Forbidden, but specifically for use when authentication is possible but has failed or not yet been provided.[2] The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. See Basic access authentication and Digest access authentication.
402 Payment Required
Reserved for future use.[2] The original intention was that this code might be used as part of some form of digital cash or micropayment scheme, but that has not happened, and this code is not usually used. As an example of its use, however, Apple's MobileMe service generates a 402 error ("httpStatusCode:402" in the Mac OS X Console log) if the MobileMe account is delinquent.
403 Forbidden
The request was a legal request, but the server is refusing to respond to it.[2] Unlike a 401 Unauthorized response, authenticating will make no difference.[2]
404 Not Found
The requested resource could not be found but may be available again in the future.[2] Subsequent requests by the client are permissible.
405 Method Not Allowed
A request was made of a resource using a request method not supported by that resource;[2] for example, using GET on a form which requires data to be presented via POST, or using PUT on a read-only resource.
406 Not Acceptable
The requested resource is only capable of generating content not acceptable according to the Accept headers sent in the request.[2]
407 Proxy Authentication Required
The client must first authenticate itself with the proxy.[2]
408 Request Timeout
The server timed out waiting for the request.[2] According to W3 HTTP specifications: "The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time."
409 Conflict
Indicates that the request could not be processed because of conflict in the request, such as an edit conflict.[2]
410 Gone
Indicates that the resource requested is no longer available and will not be available again.[2] This should be used when a resource has been intentionally removed and the resource should be purged. Upon receiving a 410 status code, the client should not request the resource again in the future. Clients such as search engines should remove the resource from their indices. Most use cases do not require clients and search engines to purge the resource, and a "404 Not Found" may be used instead.
411 Length Required
The request did not specify the length of its content, which is required by the requested resource.[2]
412 Precondition Failed
The server does not meet one of the preconditions that the requester put on the request.[2]
413 Request Entity Too Large
The request is larger than the server is willing or able to process.[2]
414 Request-URI Too Long
The URI provided was too long for the server to process.[2]
415 Unsupported Media Type
The request entity has a media type which the server or resource does not support.[2] For example, the client uploads an image as image/svg+xml, but the server requires that images use a different format.
416 Requested Range Not Satisfiable
The client has asked for a portion of the file, but the server cannot supply that portion.[2] For example, if the client asked for a part of the file that lies beyond the end of the file.
417 Expectation Failed
The server cannot meet the requirements of the Expect request-header field.[2]
418 I'm a teapot (RFC 2324)
This code was defined in 1998 as one of the traditional IETF April Fools' jokes, in RFC 2324Hyper Text Coffee Pot Control Protocol, and is not expected to be implemented by actual HTTP servers. However, known implementations do exist.[13]
422 Unprocessable Entity (WebDAV) (RFC 4918)
The request was well-formed but was unable to be followed due to semantic errors.[7]
423 Locked (WebDAV) (RFC 4918)
The resource that is being accessed is locked.[7]
424 Failed Dependency (WebDAV) (RFC 4918)
The request failed due to failure of a previous request (e.g. a PROPPATCH).[7]
425 Unordered Collection (RFC 3648)
Defined in drafts of "WebDAV Advanced Collections Protocol",[14] but not present in "Web Distributed Authoring and Versioning (WebDAV) Ordered Collections Protocol".[15]
426 Upgrade Required (RFC 2817)
The client should switch to a different protocol such as TLS/1.0.[16]
428 Precondition Required
The origin server requires the request to be conditional. Intended to prevent "the 'lost update' problem, where a client GETs a resource's state, modifies it, and PUTs it back to the server, when meanwhile a third party has modified the state on the server, leading to a conflict."[17] Proposed in an Internet-Draft.
429 Too Many Requests
The user has sent too many requests in a given amount of time. Intended for use with rate limiting schemes. Proposed in an Internet-Draft.[17]
431 Request Header Fields Too Large
The server is unwilling to process the request because either an individual header field, or all the header fields collectively, are too large. Proposed in an Internet-Draft.[17]
444 No Response
An nginx HTTP server extension. The server returns no information to the client and closes the connection (useful as a deterrent for malware).
449 Retry With
A Microsoft extension. The request should be retried after performing the appropriate action.[18]
450 Blocked by Windows Parental Controls
A Microsoft extension. This error is given when Windows Parental Controls are turned on and are blocking access to the given webpage.[19]
499 Client Closed Request
An Nginx HTTP server extension. This code is introduced to log the case when the connection is closed by client while HTTP server is processing its request, making server unable to send the HTTP header back.[20]

[edit]5xx Server Error

The server failed to fulfill an apparently valid request.[2]

Response status codes beginning with the digit "5" indicate cases in which the server is aware that it has encountered an error or is otherwise incapable of performing the request. Except when responding to a HEAD request, the server should include an entity containing an explanation of the error situation, and indicate whether it is a temporary or permanent condition. Likewise, user agents should display any included entity to the user. These response codes are applicable to any request method.

500 Internal Server Error
A generic error message, given when no more specific message is suitable.[2]
501 Not Implemented
The server either does not recognise the request method, or it lacks the ability to fulfill the request.[2]
502 Bad Gateway
The server was acting as a gateway or proxy and received an invalid response from the upstream server.[2]
503 Service Unavailable
The server is currently unavailable (because it is overloaded or down for maintenance).[2] Generally, this is a temporary state.
504 Gateway Timeout
The server was acting as a gateway or proxy and did not receive a timely response from the upstream server.[2]
505 HTTP Version Not Supported
The server does not support the HTTP protocol version used in the request.[2]
506 Variant Also Negotiates (RFC 2295)
Transparent content negotiation for the request results in a circular reference.[21]
507 Insufficient Storage (WebDAV) (RFC 4918)
The server is unable to store the representation needed to complete the request.[7]
508 Loop Detected (WebDAV) (RFC 5842)
The server detected an infinite loop while processing the request (sent in lieu of 208).
509 Bandwidth Limit Exceeded (Apache bw/limited extension)
This status code, while used by many servers, is not specified in any RFCs.
510 Not Extended (RFC 2774)
Further extensions to the request are required for the server to fulfill it.[22]
511 Network Authentication Required
The client needs to authenticate to gain network access. Intended for use by intercepting proxies used to control access to the network (e.g. "captive portals" used to require agreement to Terms of Service before granting full Internet access via a Wi-Fi hotspot). Proposed in an Internet-Draft.[17]

아래는 HTTP(하이퍼텍스트 전송 프로토콜) 응답 상태 코드의 목록이다.

IANA가 현재 공식 HTTP 상태 코드 레지스트리를 관리하고 있다.

목차

  [숨기기

1xx (조건부 응답)[편집]

요청을 받았으며 작업을 계속한다.[1]

  • 100(계속): 요청자는 요청을 계속해야 한다. 서버는 이 코드를 제공하여 요청의 첫 번째 부분을 받았으며 나머지를 기다리고 있음을 나타낸다.
  • 101(프로토콜 전환): 요청자가 서버에 프로토콜 전환을 요청했으며 서버는 이를 승인하는 중이다.
  • 102(처리, RFC 2518)

2xx (성공)[편집]

이 클래스의 상태 코드는 클라이언트가 요청한 동작을 수신하여 이해했고 승낙했으며 성공적으로 처리했음을 가리킨다.

  • 200(성공): 서버가 요청을 제대로 처리했다는 뜻이다. 이는 주로 서버가 요청한 페이지를 제공했다는 의미로 쓰인다.
  • 201(작성됨): 성공적으로 요청되었으며 서버가 새 리소스를 작성했다.
  • 202(허용됨): 서버가 요청을 접수했지만 아직 처리하지 않았다.
  • 203(신뢰할 수 없는 정보): 서버가 요청을 성공적으로 처리했지만 다른 소스에서 수신된 정보를 제공하고 있다.
  • 204(콘텐츠 없음): 서버가 요청을 성공적으로 처리했지만 콘텐츠를 제공하지 않는다.
  • 205(콘텐츠 재설정): 서버가 요청을 성공적으로 처리했지만 콘텐츠를 표시하지 않는다. 204 응답과 달리 이 응답은 요청자가 문서 보기를 재설정할 것을 요구한다(예: 새 입력을 위한 양식 비우기).
  • 206(일부 콘텐츠): 서버가 GET 요청의 일부만 성공적으로 처리했다.
  • 207(다중 상태, RFC 4918)
  • 208(이미 보고됨, RFC 5842)
  • 226 IM Used (RFC 3229)

3xx (리다이렉션 완료)[편집]

클라이언트는 요청을 마치기 위해 추가 동작을 취해야 한다.[1]

  • 300(여러 선택항목): 서버가 요청에 따라 여러 조치를 선택할 수 있다. 서버가 사용자 에이전트에 따라 수행할 작업을 선택하거나, 요청자가 선택할 수 있는 작업 목록을 제공한다.
  • 301(영구 이동): 요청한 페이지를 새 위치로 영구적으로 이동했다. GET 또는 HEAD 요청에 대한 응답으로 이 응답을 표시하면 요청자가 자동으로 새 위치로 전달된다.
  • 302(임시 이동): 현재 서버가 다른 위치의 페이지로 요청에 응답하고 있지만 요청자는 향후 요청 시 원래 위치를 계속 사용해야 한다.
  • 303(기타 위치 보기): 요청자가 다른 위치에 별도의 GET 요청을 하여 응답을 검색할 경우 서버는 이 코드를 표시한다. HEAD 요청 이외의 모든 요청을 다른 위치로 자동으로 전달한다.
  • 304(수정되지 않음): 마지막 요청 이후 요청한 페이지는 수정되지 않았다. 서버가 이 응답을 표시하면 페이지의 콘텐츠를 표시하지 않는다. 요청자가 마지막으로 페이지를 요청한 후 페이지가 변경되지 않으면 이 응답(If-Modified-Since HTTP 헤더라고 함)을 표시하도록 서버를 구성해야 한다.
  • 305(프록시 사용): 요청자는 프록시를 사용하여 요청한 페이지만 액세스할 수 있다. 서버가 이 응답을 표시하면 요청자가 사용할 프록시를 가리키는 것이기도 하다.
  • 307(임시 리다이렉션): 현재 서버가 다른 위치의 페이지로 요청에 응답하고 있지만 요청자는 향후 요청 시 원래 위치를 계속 사용해야 한다.
  • 308(영구 리다이렉션, RFC에서 실험적으로 승인됨)

4xx (요청 오류)[편집]

4xx 클래스의 상태 코드는 클라이언트에 오류가 있음을 나타낸다.

  • 400(잘못된 요청): 서버가 요청의 구문을 인식하지 못했다.
  • 401(권한 없음): 이 요청은 인증이 필요한다. 서버는 로그인이 필요한 페이지에 대해 이 요청을 제공할 수 있다.
  • 403(금지됨): 서버가 요청을 거부하고 있다.
  • 404(찾을 수 없음): 서버가 요청한 페이지를 찾을 수 없다. 예를 들어 서버에 존재하지 않는 페이지에 대한 요청이 있을 경우 서버는 이 코드를 제공한다.
  • 405(허용되지 않는 방법): 요청에 지정된 방법을 사용할 수 없다.
  • 406(허용되지 않음): 요청한 페이지가 요청한 콘텐츠 특성으로 응답할 수 없다.
  • 407(프록시 인증 필요): 이 상태 코드는 401(권한 없음)과 비슷하지만 요청자가 프록시를 사용하여 인증해야 한다. 서버가 이 응답을 표시하면 요청자가 사용할 프록시를 가리키는 것이기도 한다.
  • 408(요청 시간초과): 서버의 요청 대기가 시간을 초과하였다.
  • 409(충돌): 서버가 요청을 수행하는 중에 충돌이 발생했다. 서버는 응답할 때 충돌에 대한 정보를 포함해야 한다. 서버는 PUT 요청과 충돌하는 PUT 요청에 대한 응답으로 이 코드를 요청 간 차이점 목록과 함께 표시해야 한다.
  • 410(사라짐): 서버는 요청한 리소스가 영구적으로 삭제되었을 때 이 응답을 표시한다. 404(찾을 수 없음) 코드와 비슷하며 이전에 있었지만 더 이상 존재하지 않는 리소스에 대해 404 대신 사용하기도 한다. 리소스가 영구적으로 이동된 경우 301을 사용하여 리소스의 새 위치를 지정해야 한다.
  • 411(길이 필요): 서버는 유효한 콘텐츠 길이 헤더 입력란 없이는 요청을 수락하지 않는다.
  • 412(사전조건 실패): 서버가 요청자가 요청 시 부과한 사전조건을 만족하지 않는다.
  • 413(요청 속성이 너무 큼): 요청이 너무 커서 서버가 처리할 수 없다.
  • 414(요청 URI가 너무 김): 요청 URI(일반적으로 URL)가 너무 길어 서버가 처리할 수 없다.
  • 415(지원되지 않는 미디어 유형): 요청이 요청한 페이지에서 지원하지 않는 형식으로 되어 있다.
  • 416(처리할 수 없는 요청범위): 요청이 페이지에서 처리할 수 없는 범위에 해당되는 경우 서버는 이 상태 코드를 표시한다.
  • 417(예상 실패): 서버는 Expect 요청 헤더 입력란의 요구사항을 만족할 수 없다.
  • 418(I'm a teapot, RFC 2324)
  • 420(Enhance Your Calm, 트위터)
  • 422(처리할 수 없는 엔티티, WebDAV; RFC 4918)
  • 423(잠김,WebDAV; RFC 4918)
  • 424(실패된 의존성, WebDAV; RFC 4918)
  • 424(메쏘드 실패, WebDAV)
  • 425(정렬되지 않은 컬렉션, 인터넷 초안)
  • 426(업그레이드 필요, RFC 2817)
  • 428(전제조건 필요, RFC 6585)
  • 429(너무 많은 요청, RFC 6585)
  • 431(요청 헤더 필드가 너무 큼, RFC 6585)
  • 444(응답 없음, Nginx)
  • 449(다시 시도, 마이크로소프트)
  • 450(윈도 자녀 보호에 의해 차단됨, 마이크로소프트)
  • 451(법적인 이유로 이용 불가, 인터넷 초안)
  • 451(리다이렉션, 마이크로소프트)
  • 494(요청 헤더가 너무 큼, Nginx)
  • 495(Cert 오류, Nginx)
  • 496(Cert 없음, Nginx)
  • 497(HTTP to HTTPS, Nginx)
  • 499(클라이언트가 요청을 닫음, Nginx)

5xx (서버 오류)[편집]

서버가 유효한 요청을 명백하게 수행하지 못했음을 나타낸다.[1]

  • 500(내부 서버 오류): 서버에 오류가 발생하여 요청을 수행할 수 없다.
  • 501(구현되지 않음): 서버에 요청을 수행할 수 있는 기능이 없다. 예를 들어 서버가 요청 메소드를 인식하지 못할 때 이 코드를 표시한다.
  • 502(불량 게이트웨이): 서버가 게이트웨이나 프록시 역할을 하고 있거나 또는 업스트림 서버에서 잘못된 응답을 받았다.
  • 503(서비스를 사용할 수 없음): 서버가 오버로드되었거나 유지관리를 위해 다운되었기 때문에 현재 서버를 사용할 수 없다. 이는 대개 일시적인 상태이다.
  • 504(게이트웨이 시간초과): 서버가 게이트웨이나 프록시 역할을 하고 있거나 또는 업스트림 서버에서 제때 요청을 받지 못했다.
  • 505(HTTP 버전이 지원되지 않음): 서버가 요청에 사용된 HTTP 프로토콜 버전을 지원하지 않는다.
  • 506(Variant Also Negotiates, RFC 2295)
  • 507(용량 부족, WebDAV; RFC 4918)
