Incorrect URL: Just like the 404 error, a bad request is generated if users enter the internet address incorrectly or, for example, insert special characters that aren’t allowed.The reasons for the error report are usually related to the browser used or a user error. Therefore, it prevents the website from being properly displayed. The server has interpreted the request as faulty or even harmful. The internet protocol HTTP hasn’t been correctly adhered to (at least according to the webserver), which is why the request cannot be processed. It means that the request itself has somehow become defective. It’s not so easy to answer the question 'what’s gone wrong here?' when you’re presented with a 400 error. The cause of the message is usually either an incorrectly written URL or deleted content. The most well-known message is the 404 Not Found Error. This is quite different when it comes to error messages: while 5xx errors are related to the server, all 4xx codes relate to faulty requests from the client. Most of these extra steps have to do with forwarding, which the browser does automatically, and which you only notice in a few cases. Internet users generally see codes from 3xx and onwards: these mean that communication was successful, but that the client has to carry out an additional step. It’s a different situation when the codes 400 and 500 are shown, since this indicates different types of errors.Īll the 1xx codes are informational and all the 2xx codes are successful. The request was successful and the desired content was transferred. If the server returns the message 200 (which you don’t normally see when surfing), it means that everything is fine. With status codes, the webserver reveals the status of the requests to the client.
