Class WEBrick::CampingHandler < WEBrick::HTTPServlet::DefaultFileHandler

WEBrick::CampingHandler is a very simple handle for hosting Camping apps in a WEBrick server. It‘s used much like any other WEBrick handler.

Mounting a Camping App

Assuming Camping.goes(:Blog), the Blog application can be mounted alongside other WEBrick mounts.

  s = WEBrick::HTTPServer.new(:BindAddress => host, :Port => port)
  s.mount "/blog", WEBrick::CampingHandler, Blog
  s.mount_proc("/") { ... }

How Does it Compare?

Compared to other handlers, WEBrick is well-equipped in terms of features.

• The X-Sendfile header is supported, along with etags and modification time headers for the file served. Since this handler is a subclass of WEBrick::HTTPServlet::DefaultFileHandler, all of its logic is used.
• IO is streaming up and down. When you upload a file, it is streamed to the server‘s filesystem. When you download a file, it is streamed to your browser.

While WEBrick is a bit slower than Mongrel and FastCGI options, it‘s a decent choice, for sure!

45:         controller = @klass.run((req.body and StringIO.new(req.body)), req.meta_vars)
46:         resp.status = controller.status
47:         @local_path = nil
48:         controller.headers.each do |k, v|
49:             if k =~ /^X-SENDFILE$/i
50:                 @local_path = v
