HTTP errors are error messages that are displayed when something goes wrong with a webpage request made by a web browser. The errors are classified into different categories based on the first digit of the error code. Here are some common HTTP error codes and their descriptions:
- 4xx Client Error: These errors occur when the client (web browser) sends a bad request or the requested resource is not found. Examples include 404 Not Found and 400 Bad Request.
- 5xx Server Error: These errors occur when the server fails to fulfill a valid request. Examples include 500 Internal Server Error and 503 Service Unavailable.
- 3xx Redirection: These errors occur when the requested resource has been moved to a different location. Examples include 301 Moved Permanently and 302 Found.
It's important to understand these error codes as they can help diagnose and fix issues with web pages.
