HTTP Response / Headers

HTTP Headers Overview

The StripDNS HTTP Headers tool is built for fast, practical checks when you need reliable answers without jumping between multiple dashboards. Inspect HTTP response headers for redirects, cache, and security signals. It is especially useful for security headers and cache behavior, whether you are diagnosing outages, validating infrastructure changes, or preparing before a migration. Results are optimized for speed and readability so you can move from detection to action quickly during production incidents. For best outcomes, compare findings over time, cross-check with related DNS and TLS tools, and rerun checks after each config update to confirm changes propagated as expected.

How To Use This Tool

Common Use Cases

  • Audit security headers for policy coverage.
  • Inspect caching and redirect behavior.
  • Validate CORS and response metadata.

Recommended Steps

  1. Enter a valid domain, hostname, or IP based on the tool input format.
  2. Run the lookup and review key output fields first before deep details.
  3. Repeat after any DNS, network, or infrastructure change to confirm results.

Interpretation Tips

  • Compare results over time instead of relying on a single snapshot.
  • Cross-check with related tools for stronger confidence.
  • Document findings with timestamps during incident handling.
