10 | The web page you are watching was served by a simple web 11 | server running on top of the lightweight TCP/IP stack lwIP. 13 |

14 |

15 | The focus of the lwIP TCP/IP implementation is to reduce 16 | the RAM usage while still having a full scale TCP. This 17 | makes lwIP suitable for use in embedded systems with tens 18 | of kilobytes of free RAM and room for around 40 kilobytes 19 | of code ROM. 20 |
