<p>
The <a href="Static.html">Rack::Static</a> 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 <a
href="File.html">Rack::File</a> object. This allows a <a
href="../Rack.html">Rack</a> stack to serve both static and dynamic
content.
</p>
<p>
Examples:
</p>
<pre>
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/*)
