Overview

The Rack::TryStatic middleware delegates requests to Rack::Static middleware trying to match a static file

Examples

use Rack::TryStatic,

:root => "public",  # static files root dir
:urls => %w[/],     # match all requests
:try => ['.html', 'index.html', '/index.html'] # try these postfixes sequentially

uses same options as Rack::Static with extra :try option which is an array
of postfixes to find desired file
