lwIP - A Lightweight TCP/IP Stack

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

This page is here to test SSI, so here is a counter as an example of content changing for every request: ""

And here is an example of a tag result buffer return in multiple parts: ""

To test LWIP_HTTPD_CGI_SSI, here are the CGI parameters:

lwIP is an open source implementation of the TCP/IP protocol suite that was originally written by Adam Dunkels of the Swedish Institute of Computer Science but now is being actively developed by a team of developers distributed world-wide. Since it's release, lwIP has spurred a lot of interest and has been ported to several platforms and operating systems. lwIP can be used either with or without an underlying OS.

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