There is an example (very simple) HTTP server for the raw API in the 
contrib module (there is also a port for unix and win32 for easy 
development/debugging). The contrib module for lwIP 1.3.0 is availaible 
in the download section at savannah or via CVS.

As you mentioned you used ATMEL sample projects: be aware ATMEL could 
have an older version of lwIP, which is not really supported on this 
list. Oh, and when using the raw API: be aware the functions may only be 
called from one thread, the lwIP core is NOT thread safe (use 
sockets/netconn if you want that).

Hehe, that's a good one! Really, there is the txt files in the download, 
the pdf at adam's page (http://www.sics.se/~adam/lwip/) and (new) the 
lwIP wiki (http://lwip.wikia.com).
