HTTP (Hypertext Transfer Protocol) codes are three-digit numbers that are used by web servers to communicate with web browsers and other clients about the status of a requested web page or resource. The codes are grouped into five categories, each with a different first digit, indicating the general type of response:
1xx (Informational): These codes indicate that the server has received the request and is continuing to process it. Examples include "100 Continue" and "101 Switching Protocols."
2xx (Successful): These codes indicate that the server has successfully received, understood, and processed the request. Examples include "200 OK" and "204 No Content."
3xx (Redirection): These codes indicate that the client needs to take additional action to complete the request, such as following a redirect. Examples include "301 Moved Permanently" and "302 Found."
4xx (Client Error): These codes indicate that there was an error on the client's side of the request, such as an invalid request or unauthorized access. Examples include "400 Bad Request" and "403 Forbidden."
5xx (Server Error): These codes indicate that there was an error on the server's side of the request, such as a server malfunction or a timeout. Examples include "500 Internal Server Error" and "503 Service Unavailable."
HTTP codes are important for understanding the status of web requests and for troubleshooting issues with websites and web applications. They can be viewed in the browser's developer tools or by using a tool like cURL or Postman to send HTTP requests.
