gesendeten HTTP-Datenstrom findet. Die Methoden sind Folgende: OPTIONS: Die zur Verfügung stehenden Kommunikationsoptionen für eine bestimmte URL-Ressource herausfinden. Erlaubt dem Client die Optionen und/oder Anforderungen, die mit 501 error message einer Ressource verbunden sind oder die Möglichkeiten eines Servers, ohne spezifische Aktion,

die einen Tatentransfer beinhaltet, zu bestimmen. GET: Abrufen der durch die URL-Ressource identifizierten Informationen, z.B. GET eine bestimmte error 501 youtube Webseite oder ein Bild. Die mit Abstand gebräuchlichste Methode. HEAD: Identisch mit GET, mit der Ausnahme, dass der Server nur Headerinformationen zurückgibt, nicht die tatsächlichen durch die URL-Ressource identifizierten Informationen. http 501 error fix Nützlich, um Metainformationen über den durch die Anforderung implizierten Datensatz zu erhalten, ohne den Datensatz selbst zu transferieren. Wird häufig verwendet, um Hypertext-Links auf Gültigkeit, Erreichbarkeit und kürzliche Modifikationen hin zu prüfen. POST: Daten an den Webserver senden, wie 1) Eine Nachricht an ein Bulletin Board, eine Newsgroup oder Mailingliste posten, 2) Eingabedaten - üblicherweise aus einem CGI-Formular - an

einen Datenverarbeitungsprozess übergeben, 3) einen Eintrag direkt zu einer Datenbank hinzufügen. PUT: Die Daten für eine bestimmte URL auf die neuen, vom Client übermittelten Daten, setzen (einstellen/ersetzen). Zum Beispiel eine neue Webseite auf einen Server hochladen. DELETE: Die mit der URL-Ressource verbundenen Daten entfernen. Zum Beispiel eine Webseite löschen. TRACE: Ein entferntes Loopback der Anforderungsmeldung auf Anwendungsebene ausführen. Effektiv ein 'Ping', der prüft, was für Daten der Webserver vom Client erhält. CONNECT: Reserviert für den Einsatz mit Tunneling (z.B. SSL) über einen Proxy-Server. Diese Methode ist nur für HTTP Version 1.1 definiert, nicht für die ältere Version 1.0. Wenn die Methode im HTTP-Datenstrom der Anforderung nicht einer der obigen entspricht, tritt ein 501-Fehler auf. Oder die Methode ist gültig, wird aber tatsächlich nicht vom Webserver unterstützt. Dies passiert normalerweise nur bei neueren Methoden, wie CONNECT, wenn diese von einem älteren Webserver empfangen werden. Beheben von 501-Fehlern - allgemein Dieser Fehler sollte bei allen Webbrowsern sehr selten auftreten. Er tritt eher auf, wenn der Client kein Webbrowser ist - insbesondere wenn der Webserver alt ist.

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 https://developer.mozilla.org/en-US/docs/Web/HTTP/Status 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

It includes codes from IETF internet standards, other IETF RFCs, other specifications, and https://en.wikipedia.org/wiki/List_of_FTP_server_return_codes some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must 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 error 501 (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional 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).

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[note 1] send a 1xx response to an HTTP/1.0 client except under experimental conditions.[4] 100 Continue The server has received the request headers and 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). Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient. To have a server check the request's headers, a client must send Expect: 100-continue as a header in its initial request and receive a 100 Continue status code in response before sending the body. The response 417 Expectation Failed indicates the request should not be continued.[2] 101 Switching Protocols The requester has asked the server to switch protocols and the server has agreed to do so.[5] 102 Processing (WebDAV; RFC 2
good, bad or incomplete: Range Purpose 1xx Positive Preliminary reply The requested action is being initiated; expect another reply before proceeding with a new command. (The user-process sending another command before the completion reply would be in violation of protocol; but server-FTP processes should queue any commands that arrive while a preceding command is in progress.) This type of reply can be used to indicate that the command was accepted and the user-process may now pay attention to the data connections, for implementations where simultaneous monitoring is difficult. The server-FTP process may send at most, one 1xx reply per command. 2xx Positive Completion reply The requested action has been successfully completed. A new request may be initiated. 3xx Positive Intermediate reply The command has been accepted, but the requested action is being held in abeyance, pending receipt of further information. The user should send another command specifying this information. This reply is used in command sequence groups. 4xx Transient Negative Completion reply The command was not accepted and the requested action did not take place, but the error condition is temporary and the action may be requested again. The user should return to the beginning of the command sequence, if any. It is difficult to assign a meaning to "transient", particularly when two distinct sites (Server- and User-processes) have to agree on the interpretation. Each reply in the 4xx category might have a slightly different time value, but the intent is that the user-process is encouraged to try again. A rule of thumb in determining if a reply fits into the 4xx or the 5xx (Permanent Negative) category is that replies are 4xx if the commands can be repeated without any change in command form or in properties of the User or Server (e.g., the command is spelled the same with the same arguments used; the user does not change his file access or user name; the server does not put up a new implementation.) 5xx Permanent Negative Completion reply The command was not accepted and the requested action did not take place. The User-process is discouraged from repeating the exact request (in the same sequence). Even some "permanent" error conditions can be corrected, so the human user may want to direct his User-process to reinitiate the command sequence by direct action at some point in the future (e.g., after the spelling has been changed, or the user has altered his directory stat
