HTTP Status Codes: Decoding Web Responses

May 17, 2024 Ute Comments 0 Comment

In the realm of web development and internet browsing, HTTP status codes play a crucial role in the communication between clients (like your web browser) and servers. These three-digit codes provide vital information about the status of a requested resource and the outcome of the request. Understanding HTTP status codes is essential for developers, as it helps diagnose issues and ensures smooth web operations. In this blog post, we’ll decode the world of HTTP status codes, exploring their categories and significance.

What Are HTTP Status Codes?

HTTP (Hypertext Transfer Protocol) status codes are standardized responses given by web servers when they receive a request from a client. These codes are part of the HTTP (Hypertext Transfer Protocol) and are used to indicate the result of the request. They are divided into five classes, each represented by the first digit of the code:

1xx: Informational
2xx: Success
3xx: Redirection
4xx: Client Errors
5xx: Server Errors

Let’s delve into each category to understand their meanings and common codes.

1xx: Informational

The 1xx class indicates that the request has been received and is being processed. These codes are provisional and rarely seen in everyday browsing. Common 1xx status codes include:

100 Continue: The server has received the request headers, and the client should proceed to send the request body.
101 Switching Protocols: The server is switching protocols as requested by the client, usually in response to an Upgrade header.

2xx: Success

The 2xx class signifies that the request was successfully received, understood, and accepted. Common 2xx status codes include:

200 OK: The request was successful, and the server is returning the requested resource.
201 Created: The request was successful, and a new resource has been created as a result.
202 Accepted: The request has been accepted for processing, but the processing is not yet complete.
204 No Content: The request was successful, but there is no content to send in the response.

3xx: Redirection

The 3xx class indicates that further action is needed to complete the request. This often involves redirecting the client to another URL. Common 3xx status codes include:

301 Moved Permanently: The requested resource has been permanently moved to a new URL.
302 Found: The requested resource is temporarily available at a different URL.
304 Not Modified: The resource has not been modified since the last request, allowing the client to use a cached version.

4xx: Client Errors

The 4xx class signifies errors caused by the client. These errors occur when the request contains incorrect syntax or cannot be fulfilled. Common 4xx status codes include:

400 Bad Request: The server cannot process the request due to a client error (e.g., malformed request syntax).
401 Unauthorized: The request requires authentication, and the client has not provided valid credentials.
403 Forbidden: The server understands the request but refuses to authorize it.
404 Not Found: The requested resource could not be found on the server.
408 Request Timeout: The server timed out waiting for the request from the client.

5xx: Server Errors

The 5xx class indicates that the server encountered an error while processing the request. These errors are usually not the client’s fault. Common 5xx status codes include:

500 Internal Server Error: The server encountered an unexpected condition that prevented it from fulfilling the request.
502 Bad Gateway: The server received an invalid response from an upstream server.
503 Service Unavailable: The server is currently unable to handle the request, often due to temporary overload or maintenance.
504 Gateway Timeout: The server did not receive a timely response from an upstream server.
