I was very impressed by libwebsockets, when I was using it on NuttX a couple of years ago. It is not exactly lightweight, and much more than a webserver, but it is a perfect infrastructure component for implementing Web UIs for embedded applications. There is probably quite some porting effort to do, but you might want to have a look: https://github.com/warmcat/libwebsockets Bye, Michael On Thu, Jun 26, 2025 at 8:07 PM Tim Hardisty <t...@jti.uk.com.invalid> wrote: > Update as I am back on this after a break and still stumped. > > uIP: > > - only supports GET method > - HTML5 maps PUT to GET which is why I found either caused my CGI app > to run > - But no support for getting the data itself as...it only supports the > GET method > > thttpd: > > - supports POST, and calls my CGI app where I can save the file that's > sent > - Any calls to puts or printf from within the CGI app fail.
