You can find the old MetaCard HTTP server example at:
<http://futura.disca.upv.es/~smm/public_xml/Software/MetaCard/metacard.com-mirror-2.5/mchttpd.zip>

While it only supports the 'GET' method, it's a great
start for loearning how any socket-based server should
be built. RevOnRockets was inspired by it, as well as
several custom embedded web servers (I've built a few
myself)

Hope this helped,
