an empty line. There are no required headers for this class of http status 404 error in tomcat 8 status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a 1xx response to http status 404 error in tomcat 7 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 http://whatis.techtarget.com/definition/404-status-code 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 https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html a request, 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 ver

For example, if a https://www.youtube.com/watch?v=-FAlKbpPL9Q user follows a link and the target page does not exist anymore, the webserver should show a 404 error page. This is not the only job of a 404 error page, though. When configured correctly, it informs the Google-Bot if http status a document actually exists. To ensure this happens the way it should, it is important that a 404 error page returns the correct HTTP status code 404 - otherwise the 404 page is defective.
