Created page with "ValExtLinks prints the HTTP response code for each link (except EI and IW links) in parentheses after the OK/NG/RD status of the link. Based on wp:List_of_HTTP_status_codes|..."

New page

ValExtLinks prints the HTTP response code for each link (except EI and IW links) in parentheses after the OK/NG/RD status of the link. Based on [[wp:List_of_HTTP_status_codes|this Wikipedia list]], following are the codes understood by ValExtLinks. The [[../Curl codes|'curl' code]] comes after each HTTP response code in parentheses.
__NOTOC__
==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.

==3xx: Redirection==
This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection.

;301 Moved Permanently
:This and all future requests should be directed to the given URI.

;302 Found
:This is an example of industry practice contradicting the standard. The HTTP/1.0 specification required the client to perform a temporary redirect (the original describing phrase was "Moved Temporarily"), 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 behaviors. However, some Web applications and frameworks use the 302 status code as if it were the 303.

;303 See Other
:The response to the request can be found under another URI using a GET method.

;307 Temporary Redirect
:The request should be repeated with another URI; however, future requests should still use the original URI.

;308 Permanent Redirect
:The request and all future requests should be repeated using another URI.

==4xx: Client Errors==
This class of status codes is intended for situations in which the client seems to have erred.

;400 Bad Request
:The server cannot or will not process the request due to an apparent client error (e.g., malformed request syntax).

;401 Unauthorized
:Similar to 403 Forbidden, but specifically for use when authentication is required and has failed or has not yet been provided.

;403 Forbidden
:The request was valid, but the server is refusing action. The user might not have the necessary permissions for a resource.

;404 Not Found
:The requested resource could not be found but may be available in the future. Subsequent requests by the client are permissible.

;405 Method Not Allowed
:A request method is not supported for the requested resource; for example, a GET request on a form that requires data to be presented via POST, or a PUT request on a read-only resource.

;406 Not Acceptable
:The requested resource is capable of generating only content not acceptable according to the Accept headers sent in the request.

;410 Gone
:Indicates that the resource requested is no longer available and will not be available again. 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 in the future.

;418 I'm a teapot
:This is a joke response code used by some sites. Probably equivalent to a 200.

==5xx: Server Errors==
These codes mean that the server failed to fulfill an apparently valid request.

;500 Internal Server Error
:A generic error message, given when an unexpected condition was encountered and no more specific message is suitable.

;501 Not Implemented
:The server either does not recognize the request method, or it lacks the ability to fulfill the request. Usually this implies future availability (e.g., a new feature of a web-service API).

;502 Bad Gateway
:The server was acting as a gateway or proxy and received an invalid response from the upstream server.

;503 Service Unavailable
:The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state.

;530 Site is frozen
:Some Internet companies use this to indicate that a site is down, but usage is non-standard, so the site will have to be tried again later to see if the outage is due to a frozen account or something else.
