What Are HTTP Status Codes? 
HTTP status codes are numeric signals that allow web servers and clients (like browsers) to communicate efficiently. They tell you whether a request worked, failed, or encountered an issue. Every web developer should understand them to build reliable websites and apps.Common HTTP Status Codes Explained 
Here are some of the most important codes you’ll encounter:- 200 OK - The request was successful, and the server returned the expected content.
- 404 Not Found - The requested page or resource doesn’t exist. Perfect for handling broken links.
- 500 Internal Server Error - Something went wrong on the server side. Often requires debugging and server checks.
Other useful codes include:
- 301 Moved Permanently - The resource has been moved to a new URL.
- 302 Found - Temporary redirect to another page.
- 403 Forbidden - Access denied; the client doesn’t have permission.
- 400 Bad Request - The server cannot process the request due to invalid syntax.
Why Understanding HTTP Codes Matters 
Knowing HTTP status codes is key for:- Troubleshooting website errors: Quickly identify server or client issues.
- Improving user experience: Show proper messages for 404 pages or redirect users smoothly.
- Enhancing web applications: Optimize API calls and server responses.
- SEO benefits: Search engines interpret status codes to index your site correctly.
Tips for Developers 
- Use custom error pages for 404 and 500 codes to keep visitors engaged.
- Monitor server logs to catch recurring 500 errors.
- Test your APIs and website responses regularly using tools like Postman or cURL.
- Always ensure redirects (301/302) are implemented correctly to avoid SEO penalties.
Conclusion 
Mastering HTTP status codes is essential for any web developer. From handling server errors to improving client requests, these codes empower you to troubleshoot efficiently and build reliable, user-friendly web applications. Last edited:
