#Network error 404 not found password
This is commonly known as password protection. 401 : UnauthorizedĪccess to the URL resource requires user authentication, which either has not yet been provided or which has been provided but failed. This almost universally indicates an error with the programming, either in the client or in the server. This indicates that the request was not in a format that the server understood and could not be served. When the HTTP request completely fails to conform to the HTTP protocol, the Web server may identify it as being malformed and serve this error page. The request may be incorrect, or the resource may have been removed, but the server is functioning correctly, and the error is that the user is requesting something that is not there.Ĭontinue reading for an index of possible 4XX Client Error Codes. A Client Error Code indicates an issue with the request and that the request itself must be changed to get a different result.įor example, if you get a 404 error code, it means the resource you requested does not exist. This article will cover the following codes:Ĭlient Error Codes begin with the number 4, such as 404 or 403 (two of the most common client-side errors). There are 5 classes of status codes, and the term error codes specifically refer to the two classes of status codes that indicate these errors. However, your browser will generally only display a status code associated with an error after an attempted action fails.

It indicates that a resource has permanently gone (a 404 status code gives no indication if a resource has gone permanently or temporarily), and no new address is known for it.Ī 415 status code is returned by a server to indicate that part of the request was in an unsupported format.All HTTP requests (the type of requests generated by your browser when you attempt to load a page) generate a status code. A server is set to only wait a certain amount of time for responses from clients, and a 408 status code indicates that time has passed.Ī 410 status code is the 404's lesser known cousin. The best known of them all, the 404 status code indicates that the requested resource was not found at the URL given, and the server has no idea how long for.Ī 408 status code means that the client did not produce a request quickly enough. That might mean that the wrong username and password were sent in the request, or that the permissions on the server do not allow what was being asked. It's interesting to think about how this will be used in the future, especially now that Chrome natively blocks some intrusive ads.Ī 403 status code indicates that the client cannot access the requested resource. The 402 status code is not currently in use, being listed as "reserved for future use". This type of status code is intended for situations in which an error seems to have been caused by the browser or user, like the infamous 404 error.Ī status code of 400 indicates that the server did not understand the request due to bad syntax.Ī 401 status code indicates that before a resource can be accessed, the client must be authorised by the server. 307 was created as another, less ambiguous, version of the 302 status code. There is very little difference between a 302 status code and a 307 status code. 307 - Temporary Redirectģ07 is the status code that is sent when a document is temporarily available at a different URL, which is also returned. If not, the client just reloads the document from the cache. The next time the document is viewed, the client asks the server if the document has changed. Normally, when a document is cached, the date it was cached is stored. The 304 status code is sent in response to a request (for a document) that asked for the document only if it was newer than the one the client already had. It also tells the browser which URL to use the next time it wants to fetch it. The response should also include the location. This tells a browser that the resource it asked for has permanently moved to a new location. The response will also include a list of new locations so the browser can pick a place to redirect to. The 300 status code indicates that a page or document has moved. Many of these status codes are used in URL redirection. These status codes tell the browser that it must take additional action to complete the request.
