This allows a <a href="../Rack.html">Rack</a> stack to serve both static and dynamic content. </p> <p> Examples: </p> <p> Serve all requests beginning with /media from the "media" folder located in the current directory (ie media/*): </p> <pre> use Rack::Static, :urls => ["/media"] </pre> <p> Serve all requests beginning with /css or /images from the folder "public" in the current directory (ie public/css/* and public/images/*): </p> <pre> use Rack::Static, :urls => ["/css", "/images"], :root => "public" </pre> <p> Serve all requests to / with "index.html" from the folder "public" in the current directory (ie public/index.html): </p> <pre> use Rack::Static, :urls => {"/" => 'index.html'}, :root => 'public' </pre> <p> Serve all requests normally from the folder "public" in the current directory but uses index.html as default route for "/" </p> <pre> use Rack::Static, :urls => [""], :root => 'public', :index => 'index.html' </pre> <p> Set custom HTTP Headers for based on rules: </p> <pre> use Rack::Static, :root => 'public', :header_rules => [ [rule, {header_field => content, header_field => content}], [rule, {header_field => content}] ] Rules for selecting files: 1) All files Provide the :all symbol :all => Matches every file 2) Folders Provide the folder path as a string '/folder' or '/folder/subfolder' => Matches files in a certain folder 3) File Extensions Provide the file extensions as an array ['css', 'js'] or %w(css js) => Matches files ending in .css or .js 4) Regular Expressions / Regexp Provide a regular expression %r{\.(?:css|js)\z} => Matches files ending in .css or .js /\.(?:eot|ttf|otf|woff|svg)\z/ => Matches files ending in the most common web font formats (.eot, .ttf, .otf, .woff, .svg) Note: This Regexp is available as a shortcut, using the :fonts rule 5) Font Shortcut Provide the :fonts symbol :fonts => Uses the Regexp rule stated right above to match all common web font endings Rule Ordering: Rules are applied in the order that they are provided. List rather general rules above special ones.
