The Web Server

The router includes a high performance web server lighttpd, known as "Lighty" which, if additional storage is provided on the USB port of the router, you can use to provide public facing web services.

You can use this web server to publish your own static content which can be available all the time, rather than just when your home computers are powered up. Lighty supports CGI, so more ambitious web applications are possible within the limits of what is available in OpenWrt; the usual security issues apply.
