module Rack
# 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/*)
