HTTP headers are key elements of interaction between the client (browser) and the server, defining data transmission parameters. They contain crucial information affecting SEO, security, and website performance.
Why Check HTTP Headers?
- SEO optimization — headers influence page indexing and visibility.
- Redirect analysis — checking 301, 302, 307, and 308, which direct users to another URL.
- Caching diagnostics — headers like Cache-Control, Expires, and ETag help speed up page loading.
- Website security — headers such as X-Frame-Options and Content-Security-Policy protect against attacks.
- Error control — checking 4xx (client errors) and 5xx (server errors).
Key HTTP Status Codes
- 1xx — Informational (e.g., 101 Switching Protocols).
- 2xx — Successful (200 OK, 201 Created, 204 No Content).
- 3xx — Redirections (301 Moved Permanently, 302 Found, 307 Temporary Redirect, 308 Permanent Redirect).
- 4xx — Client Errors (404 Not Found, 403 Forbidden, 429 Too Many Requests).
- 5xx — Server Errors (500 Internal Server Error, 503 Service Unavailable).
