UNDERSTAND THE TOOL
What is HTTP Header Checker?
Response headers reveal caching behavior, security policies, server software, redirects and content type for a URL.
Use it to confirm HTTPS redirects, security headers, cache-control settings and CDN behavior after a deployment.
READ THE OUTPUT
How to understand your results
Three signals that matter most when interpreting this tool.
Security headers
Look for headers such as Strict-Transport-Security and Content-Security-Policy.
Caching behavior
Cache-Control and ETag headers reveal how a CDN or browser may cache the response.
HOSTGRABER EXPERT GUIDE
Diagnosing a site from its response headers
HTTP response headers describe caching, security policy, server software and redirect behavior before the page body is even read. They are one of the fastest ways to confirm a deployment, CDN or security change actually took effect.
After enabling HTTPS, a CDN or a security header, recheck the live response to confirm the header is present with the expected value, since browser caching or an intermediate proxy can otherwise mask a misconfiguration.
PRACTICAL GUIDE
Getting a reliable answer from this tool
Network and TLS diagnostics are snapshots of a specific path and time. Routing, firewalls, CDN layers, certificate chains and regional peering can change what one test server sees. Repeat important checks and compare them with application monitoring before drawing a conclusion.
When troubleshooting production services, capture the hostname, destination, time of test and expected behaviour. That context makes latency, routing or certificate results far more actionable.

COMMON QUESTIONS
HTTP Header Checker FAQ
Clear answers for common http header checker questions.
Why do I only see one redirect result?+
The checker follows a limited number of redirects and reports the final response reached.
Can this check a page behind login?+
No. It sends an unauthenticated request, so protected pages will return their public response, such as a login redirect.
Does this tool modify my website?+
No. It only sends a read-only request and displays the response it receives.
