What is an HTTP Header Checker?
An HTTP Header Checker allows you to inspect the raw response headers returned by a web server. These headers contain essential information about the server software, content type, caching policies, and security configurations.
Why check HTTP Headers?
- Security Audit: Verify if essential security headers like Strict-Transport-Security or X-Frame-Options are active.
- Debugging: Check HTTP status codes (200 OK, 301 Redirect, 404 Not Found, 500 Error).
- SEO & Caching: Inspect cache-control directives and content encoding to optimize performance.
Frequently Asked Questions
What does a 200 OK status mean?
A 200 OK status means the request was successful and the server returned the requested data without any errors or redirects.
Can I check APIs with this tool?
Yes! You can enter any public REST API endpoint URL to inspect its response headers and content types.
