If LwIP sends a RST packet to close the connection, then it's because
you didn't read all the data from the browser.
(you must read all headers until the double CRLF, and not just the first
line)

This is a common behavior of TCP/IP stacks.
Look in the documentation of the function tcp_close_shutdown() in tcp.c

Yes.
