Nelson Neves / GSL_05-HttpServer-WebFS

Simple code to demonstrate how to mount the internal flash and deploy files via http server requests (http://mbed_ip_address/demo.htm) Note: Demo program to be used on the GeekSessionLab Talk (November 2011). http://devrendezvous.com/?lang=en

Dependencies:   EthernetNetIf mbed HTTPServer
