Class: Rack::Static
- Defined in:
- lib/action_controller/vendor/rack-1.0/rack/static.rb
Overview
The Rack::Static middleware intercepts requests for static files (javascript files, images, stylesheets, etc) based on the url prefixes passed in the options, and serves them using a Rack::File object. This allows a Rack stack to serve both static and dynamic content.
Examples:
use Rack::Static, :urls => ["/media"]
will serve all requests beginning with /media from the "media" folder
located in the current directory (ie media/*).
use Rack::Static, :urls => ["/css", "/images"], :root => "public"
will serve all requests beginning with /css or /images from the folder
"public" in the current directory (ie public/css/* and public/images/*)
