That's a TODO for the httpd included in lwIP contrib...

Just so you know, it's the same with the socket API of windows or linux: 
it's not guaranteed that you get as much data as you request in the len 
parameter. The recv() call may return as much data as is available: if 
only the first packet of a splitted request is received, you will get 
that instead of the full request! lwIP is not different in this case.
