In short, when we try to access a certain page, our browser sends a request to the web server which, in turn, will respond with a three-digit numerical code useful for defining the outcome of the request .Here, the status code serves precisely to communicate whether the resource requested by the client from the server is available or not and why . All summarized in the three numbers reported in the state code (e.g. 404 ). The first number ( 4 ) is the most important one because it immediately gives essential information, the outcome of the request :1xx, 2xx, 3xx : the request can be satisfied;4xx and 5xx : The request failed due to errors.How (and where) to find Status Codes: all the Tools.Every browser is now equipped with an inspect function with Special Data which we can carry out various analysis activities such as accessing the network tab .
