Caddy webserver goes south
Caddy-Sponsors HTTP Header
As of version 0.10.9, Caddy emits an HTTP response header, Caddy-Sponsors, which is similar to the Server header that Caddy already has, except that this one credits our sponsors who make it possible to keep Caddy free for personal use. This header cannot be removed by the Caddyfile, and its presence is required by the non-commercial EULA. This requirement is waived by the commercial license, so the header is not present in those binaries.
