Class Rack::Static
In: lib/rack/static.rb
Parent: Object

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/*)
