Frequently Asked Questions

Where can I find HTTP headers?▾

In browser DevTools Network tab, select any request and view the Headers section. You can also use curl -v or server logs.

What are security headers?▾

Security headers like X-Frame-Options, Content-Security-Policy, and Strict-Transport-Security help protect against common web vulnerabilities.

Why is caching important?▾

Caching headers (Cache-Control, ETag, Last-Modified) reduce bandwidth, improve performance, and decrease server load by allowing browsers to reuse cached resources.
