For Legal Reasons v t e This is a list of http 502 Hypertext Transfer Protocol (HTTP) response status codes. It includes codes from IETF internet standards, other IETF http 504 RFCs, other specifications, and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must http://www.w3schools.com/tags/ref_httpmessages.asp recognise these five classes at a minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional https://en.wikipedia.org/wiki/List_of_HTTP_status_codes decimal sub-codes to provide more specific information,[3] but not all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).

HTTP status codes are three-digit codes, and are grouped into five different classes. The class of a status code can be quickly identified by its first digit: 1xx: Informational 2xx: Success 3xx: Redirection 4xx: Client Error 5xx: Server Error This guide html web error 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, 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

Responses are grouped in five 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 201 Created The request has succeeded and a new resource has been created as a result of it. This is typically the response sent after a PUT request. 202 Accepted The request has been received but not yet acted upon. It is non-committal, meaning that there is no way in HTTP to later send an asynchronous response indicating the outcome of processing the request. It is intended for cases where another process or server handles the request, or for batch processing. 203 Non-Authoritative Information This response code means returned meta-information set is not exact set as available from the origin server, but collected from a local or a third party copy.
