Cache Header Checker

Cache Header Checker helps webmasters inspect performance signals that can be checked from a VPS using public HTTP responses, DNS data, HTML parsing, generated files or server-side validation. It is designed to return a compact report with the result, the signal checked and the next action to take.

What the Cache Header Checker does

Cache Header Checker focuses on response timing, payload weight, optimization hints. Use it when you need a quick, public check that can be repeated before and after changes. Frabs runs the check server-side against the public URL or domain and turns the result into a compact report with clear pass, warning and critical statuses.

The report focuses on response timing, payload weight, optimization hints so you can see the useful signals without digging through raw page source, DNS output or server headers by hand.

Why it matters

Cache Header Checker supports technical quality by making performance issues easier to find, explain and retest. Frabs keeps the output practical: enough detail to show what is wrong, where to look and what to fix next, without turning the page into a noisy dashboard.

Typical problems this tool helps expose include slow response, uncompressed assets, heavy javascript or css. These are small on their own, but they often become bigger during launches, migrations and template changes.

How to use it

  1. 1. Enter the full page or domain you want to inspect.
  2. 2. Run the free check and wait while Frabs fetches public signals.
  3. 3. Read the report summary first, then open the detailed result rows.
  4. 4. Save the Cache Header Checker result with the URL or domain checked, the date and the fix you applied.
  5. 5. Retest after changes so the report reflects the live website.
