code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a 1xx response to http status codes cheat sheet an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not

expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, http 422 then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is

some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client http response example 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 (RFC https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html 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 2518) A WebDAV request
Syntax' hat, d.h. sich nicht völlig an das HTTP-Protokoll gehalten hat. Daher war der Webserver nicht in der Lage, die Anforderung zu verstehen http://www.checkupdown.com/status/E400.html und sie zu verarbeiten. Dies bedeutet fast immer eine schlechte Programmierung des Client-Systems und/oder des Webservers. Beheben von 400-Fehlern - allgemein Es liegt ein Low-Level-Problem im Client oder Webserver oder beiden vor. In 95 % der Fälle liegt dies an einem Problem im Client-System, z.B. ist etwas instabil auf Ihrem PC, auf dem http error der Webbrowser läuft. Ist Ihr PC geschützt? Wenn Ihr PC nicht gut geschützt ist, können alle Arten von Fehlern auftreten - einschließlich HTTP 400-Fehlern. Wenn Sie Windows als Betriebssystem verwenden, halten Sie Ihren Computer mit den automatischen Sicherheitsupdates von Microsoft aktuellsten Stand und überlegen Sie sich einen Registry Cleaner anzuschaffen. Sorgen Sie immer für http error status guten Antiviren- und Spyware-Schutz. Investieren Sie in eine Hardware-Firewall, wenn diese für Sie erschwinglich ist. Surfen Sie bewusst im Web - blockieren Sie Popupfenster und vermeiden Sie gefährliche Sites. Wenn die Sicherheit Ihres PCs beeinträchtigt ist, kann der Webtraffic von Ihrem PC ins Internet insgeheim von Malware (Spyware, Viren usw.), die auf Ihrem PC läuft, korrumpiert sein. Dieses zu entdecken kann schwierig für Sie sein. Haben Sie webbasierte Software installiert? Einige Social Networking (Community) und Game Sites fordern Sie auf, Software herunterzuladen und auf Ihrem PC zu installieren, sodass Sie mit anderen Leuten im Internet direkt kommunizieren können (ohne Ihren Webbrowser zu verwenden). Diese Software kann, wenn Sie schlecht geschrieben oder sogar kriminell ist, den gesamten HTTP-Traffic von Ihrem PC korrumpieren. Diese defekte Software loszuwerden kann schwierig sein. Im schlimmsten Fall müssen Sie evtl. Ihr Betriebssystem neu installieren (dadurch verlieren Sie möglicherweise alle Ihre persönlichen Daten, wenn Sie kein Backup davon haben). Wie stabil ist Ihre Internetverbindung? Wenn S
