What a detection means
- Establishes
- One or more public signals on the scanned page matched a known HTTP/2 signature at the time of the scan.
- Does not establish
- A sitewide install of HTTP/2, an active vendor contract, exclusive use, or that HTTP/2 is still in place today.

How to check a site for HTTP/2
- 1. Enter the website URL in the scan form — homepage, pricing, checkout, or login pages usually expose the strongest HTTP/2 signals.
- 2. PluginView reads only public responses and scores them against proprietary HTTP/2 fingerprints. Rule bodies and identifiers are not published.
- 3. Review the confidence score and text explanation for HTTP/2 on the results page.
