HTTP Response Test
Check how a URL responds over HTTP. You get the status code, response time, and all headers the server sends back. Handy for debugging, verifying security headers, or seeing what an API returns before you integrate it.
Test HTTP Response
Enter a URL to see its HTTP status and headers.
How to Use This Tool
Enter a full URL (including https://) or just a domain. We send a GET request and show the first response we get. That means if the server redirects, you see the redirect response, not the final destination. For redirect chains, use our IP Redirect Checker. Here you get status, timing, and the raw header list.
Why This Tool Matters
HTTP headers carry a lot of information: security policies like Content-Security-Policy and Strict-Transport-Security, caching rules, content type, and server identification. When you're debugging why a site behaves oddly or verifying that security headers are set correctly, seeing the actual response is essential. APIs also expose useful headers (rate limits, auth requirements, content type) that help you integrate properly.
Use Cases
- Verify HSTS, CSP, or X-Frame-Options are present on your site
- Check cache headers (Cache-Control, ETag) for CDN or browser caching
- See how an API responds before writing client code
- Debug CORS or other header-related issues
FAQs
What does HTTP response test show?
Status code, response time, and the raw headers returned by the server. It helps you verify how a URL responds without loading the full page.
Why would I need to see HTTP headers?
Headers reveal security settings (CSP, HSTS), cache rules, content type, redirects, and server info. Useful for debugging and compliance.
Does the tool follow redirects?
We request with redirect: manual so you see the first response and status. For redirect chains, use our IP Redirect Checker.
Is it safe to test my site?
Yes. We send a single GET request. No form submission or sensitive data.
Can I test APIs?
Yes. Any HTTP or HTTPS URL works. APIs often return JSON and useful headers.
