Common HTTP Status Codes and Their Importance

What Are HTTP Status Codes?

HTTP status codes are three-digit numbers sent by a server to indicate the result of a client’s request. These codes are grouped into five classes:

• 1xx: Informational
  • Indicates that the request was received and is being processed.
  • Example: 100 Continue — The server has received the initial request and the client should proceed with sending the rest.
• 2xx: Success
  • Indicates that the request was successfully received, understood, and processed.
  • Example: 200 OK — The request was successful and the server is returning the requested data.
• 3xx: Redirection
  • Indicates that the client must take additional action to complete the request.
  • Example: 301 Moved Permanently — The requested resource has been permanently moved to a new URL.
• 4xx: Client Errors
  • Indicates that there was an error in the request made by the client.
  • Example: 404 Not Found — The requested resource could not be found on the server.
• 5xx: Server Errors
  • Indicates that the server failed to fulfill a valid request.
  • Example: 500 Internal Server Error — An unexpected condition prevented the server from fulfilling the request.
