00002 //
00003 // Example of HTTPServer with additional features:
00004 // * SNTP Client (Simple NTP)
00005 // * Link status indication (LED4 or RJ45 socket LED on MBED-BoB2-mod)
00006 // * Local file system (create index.htm page on MBED!)
00007 // * SD-based WebServer
00008 // * RPC-able class (myrpc, allows remote function call that blinks LED1 N times)
00009 // * Static HTML page
00010 // * Dynamic HTML page
00011 //
00012 // Instructions:
00013 // 1  Plug MBED into MBED-BoB2 (or other ETH connector breakout)
00014 // 2  Plug ETH connector into your network (needs DHCP to get IP address and Internet connection)
00015 // 3  Power up MBED using USB cable
00016 // 4  Install MBED serial driver (http://mbed.org/handbook/SerialPC)
00017 // 5  Copy compiled .bin to your MBED (make sure target device selected in the compiler is correct)
00018 // 6  Open terminal on the mbed serial port
00019 // 7  Push MBED reset button
00020 // 8  Terminal will display info message with mac address, followed by IP address (if connection succeeds)
00021 //    in the following items, replace 10.0.0.321 with actual MBED IP address from the terminal
00022 // 9  Open browser and enter the following URL:
00023 //    http://10.0.0.321/rpc/myrpc1/blink,10
00024 // 10 MBED will blink the LED 10 times
00025 // 11 Open browser and enter the following URL:
00026 //    http://10.0.0.321/rpc/myrpc1/gettime
00027 // 12 The browser will show date and time from the MBED synchronized to NTP server
00028 // 13 Open browser and enter the following URL:
00029 //    http://10.0.0.321/static.htm
00030 // 14 The browser will show static HTML page
00031 // 15 Open browser and enter the following URL:
00032 //    http://10.0.0.321/dynamic.htm
00033 // 16 The browser will show dynamic HTML page
00034 // 17 Create a simple index.htm page on the MBED
00035 // 18 Open browser and enter the following URL:
00036 //    http://10.0.0.321
00037 // 19 The browser will show index HTML page
00038 // 20 Create a simple index.htm page on a micro SD card, plug the card into MBED-BoB2
00039 // 21 Open browser and enter the following URL:
00040 //    http://10.0.0.321
00041 // 22 The browser will show index HTML page from SD card
00042 // 23 Optionally, create file "sntp.ini" on MBED or SD card. Copy-paste SNTP configuration from the terminal into this file and modify to your needs.
00043 //
00044 // Notes: there are still some bugs in HTTPServer code. 
00045 // To help fight some of them, copy a valid favicon.ico (a 16x16 icon) file to MBED.
