Understanding Server-Side Error Handling and Proving Errors on the Client Side: A Guide to Simulating HTTP Responses.
Understanding Server-Side Error Handling and Proving Errors on the Client Side Introduction to Server-Side Errors In web development, server-side errors are typically handled by the application’s error handling mechanism. When a client (usually a web browser) sends an HTTP request to a server, the server responds with an HTTP status code that indicates the outcome of the request. If there is an error on the server-side, the server will return an HTTP status code that indicates the type and severity of the error.
