1==HTTP Response Status Code Reference==
2For use with ValExtLinks script (http://wiki.oni2.net/ValExtLinks).
3Only codes encountered so far by ValExtLinks are listed here.
4Source: https://en.wikipedia.org/wiki/List_of_HTTP_status_codes
5
6
7--2xx: Success--
8This class of status codes indicates the action requested by the client was received, understood, accepted, and processed successfully.
9
10200 OK
11 Standard response for successful HTTP requests.
12
13
14--3xx: Redirection--
15This 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.
16
17301 Moved Permanently
18 This and all future requests should be directed to the given URI.
19
20302 Found
21 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.
22
23307 Temporary Redirect
24 The request should be repeated with another URI; however, future requests should still use the original URI.
25
26
27--4xx: Client Errors--
28The 4xx class of status codes is intended for situations in which the client seems to have erred.
29
30401 Unauthorized
31 Similar to 403 Forbidden, but specifically for use when authentication is required and has failed or has not yet been provided.
32
33403 Forbidden
34 The request was valid, but the server is refusing action. The user might not have the necessary permissions for a resource.
35
36404 Not Found
37 The requested resource could not be found but may be available in the future. Subsequent requests by the client are permissible.
38
39405 Method Not Allowed
40 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.
41
42406 Not Acceptable
43 The requested resource is capable of generating only content not acceptable according to the Accept headers sent in the request.
44
45410 Gone
46 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.
47
48
49--5xx: Server Errors--
50The server failed to fulfil an apparently valid request.
51
52500 Internal Server Error
53 A generic error message, given when an unexpected condition was encountered and no more specific message is suitable.
54
55501 Not Implemented
56 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).
57
58503 Service Unavailable
59 The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state.
