//
// Example of HTTPServer with additional features:
// * Link status indication (LED4)
// * Local file system (create index.htm page on MBED!)
// * RPC-able class (myrpc, allows remote function call that blinks LED1 N times)
//
// Instructions:
// 1  Plug MBED into BoB2 (or other ETH connector breakout)
// 2  Plug ETH connector into your network (needs DHCP to get IP address)
// 3  Power up MBED using USB cable
// 4  Install MBED serial driver (http://mbed.org/handbook/SerialPC)
// 5  Copy compiled .bin to your MBED (make sure target device selected in the compiler is correct)
// 6  Open terminal on the mbed serial port
// 7  Push MBED reset button
// 8  Terminal will display info message with mac address, followed by IP address (if connection succeeds)
// 9  Open browser and enter the following URL, inserting your MBED's IP address:
//    http://10.0.0.321/rpc/myrpc1/blink,10 (instead of 10.0.0.321 use MBED IP address from terminal)
// 10 MBED will blink the LED 10 times
//
// Notes: there are still some bugs in HTTPServer code. 
// To help fight some of them, copy a valid favicon.ico (a 16x16 icon) file to MBED.
