Quick facts
Detection methodology for Web servers
Server software identification reads the `Server` response header and (where exposed) version-specific markers in error pages. Cloudflare in front of nginx in front of Apache is the classic three-layer stack you'll see in the wild — we surface each layer separately so the actual origin server isn't masked by the edge layer.
How we detect Apache HTTP Server
Each signal alone is rarely conclusive — Sourcemap Explorer cross-references all of them and weights by confidence. You can reproduce any of these checks yourself in Chrome DevTools.
Server-side fingerprint: the response header reveals the technology behind the page. Visible in DevTools → Network → response headers.
Server: (?:Apache(?:$|/([\d.]+)|[^/-])|(?:^|\b)HTTPD)
FAQ
How do I check if a website is using Apache HTTP Server?
Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. The popup matches Apache HTTP Server's fingerprint signals (response headers, asset URL prefixes, runtime globals, sourcemap paths) and flags it whenever any combination is found. The same checks can be reproduced manually in DevTools — see the "How we detect" section above.
What Apache HTTP Server version can Sourcemap Explorer detect?
Apache HTTP Server ships as a hosted web servers rather than a bundled npm package, so version-specific detection isn't always possible. Where the platform leaks a version in response headers (`X-Powered-By`, `Server`, generator meta tags) we surface it; otherwise we report presence only.
Is Apache HTTP Server open source?
Yes, Apache HTTP Server is open source. The license details are listed on the official site (https://httpd.apache.org/), and the codebase typically lives on a public source-control host.
Where can I read more about Apache HTTP Server?
