00002 //
00003 // Example of HTTPServer with additional features:
00004 // * Link status indication (LED4)
00005 // * Local file system (create index.htm page on MBED!)
00006 // * RPC-able class (myrpc, allows remote function call that blinks LED1 N times)
00007 //
00008 // Instructions:
00009 // 1  Plug MBED into BoB2 (or other ETH connector breakout)
00010 // 2  Plug ETH connector into your network (needs DHCP to get IP address)
00011 // 3  Power up MBED using USB cable
00012 // 4  Install MBED serial driver (http://mbed.org/handbook/SerialPC)
00013 // 5  Copy compiled .bin to your MBED (make sure target device selected in the compiler is correct)
00014 // 6  Open terminal on the mbed serial port
00015 // 7  Push MBED reset button
00016 // 8  Terminal will display info message with mac address, followed by IP address (if connection succeeds)
00017 // 9  Open browser and enter the following URL, inserting your MBED's IP address:
00018 //    http://10.0.0.321/rpc/myrpc1/blink,10 (instead of 10.0.0.321 use MBED IP address from terminal)
00019 // 10 MBED will blink the LED 10 times
00020 //
00021 // Notes: there are still some bugs in HTTPServer code. 
00022 // To help fight some of them, copy a valid favicon.ico (a 16x16 icon) file to MBED.
