HTML5 Boilerplate's web.config file is used to configure options for your site running on an IIS7 server or higher.

As with the .htaccess file, merely having it in the root folder of your website allows it to be recognized and used to configure an IIS7 server.

As with the other configuration files, place it in the root folder for the Lighttpd server to configure the server.

Nginx is a lightweight server popular with websites using the Ruby on Rails framework.

As with the .htaccess file, place this file in the root folder of your website. In addition, make sure nginx-mime.types is also in the root folder. This file is required for Ngnix to make sure it sends each file with the right MIME type.

With the node.js configuration file, the usage is different. The configuration file assumes you are using the Express/Connect framework for managing resource requests for your app. In your server-side app code, you can use the following to start the server:

var h5bp = require('h5bp'), 
var app = express.createServer();
app.use(h5bp.server());
app.listen(3000);

This requires you to install the h5bp package using Node Package Manager (NPM) and the express package using the same. The h5bp package has a slew of configurations that will be used when the server is started. If you wish to use only some specific configurations, you can pass them in as options to the server function, as shown in the following code snippet:

app.use(h5bp.server({
server: true,
setContentType: true,
removeEtag: true
});

Some websites are also served from Google App Engine (http://code.google.com/appengine/), which requires your website's backend to be written in Java, Python, or Go.

You need to ensure that the app.yaml file is in the root folder of your website.
