About This Tool
The HTTP Response Header Inspector queries target web domains to analyze server response headers, HTTP protocol status codes, content-type directives, and web security policies. The dashboard inspects critical modern security headers including Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, and cache-control headers. Requests route through an ephemeral backend proxy endpoint to retrieve server headers without exposing client CORS restrictions. No inspected domains, query parameters, or header values are logged or persisted.
How to Use
- 1
Enter the destination website URL or domain name in the search input.
- 2
Click Scan DNS or Check Headers to initiate the server response query.
- 3
Review the HTTP status code (200 OK, 301 Redirect, etc.) and raw response headers.
- 4
Inspect security header grades and recommendations in the summary dashboard.
Frequently Asked Questions
Why does the tool require a backend proxy to check headers?
Browser security CORS policies prevent client JavaScript from reading arbitrary third-party HTTP response headers directly; requests route through an ephemeral proxy service.
Which security headers does the inspector evaluate?
The tool audits HSTS (Strict-Transport-Security), CSP (Content-Security-Policy), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
Are inspected URLs or header values saved to a database?
No. Requests are processed ephemerally in transit with zero logging or database persistence.
