This endpoint serves static files from disk using Rack::File.
URL paths are matched with static files according to expected conventions: path
, path
.html, path
/index.html.
Precompressed versions of these files are checked first. Brotli (.br) and gzip (.gz) files are supported. If path
.br exists, this endpoint returns that file with a Content-Encoding: br
header.
If no matching file is found, this endpoint responds 404 Not Found.
Pass the root
directory to search for matching files, an optional index: "index"
to change the default path
/index.html, and optional additional response headers.
