I use LwIP 1.4.1 and netconn API, allowing for example to remotely
dump flash image of STM32F4 (1MB) over EDGE router so slow c

A statement like this belongs into the bug tracker or at least in a suspected
bug report on lwip-devel, not into a side-note
Today I finally captured some debug output. Active debug options:
#define SOCKETS_DEBUG LWIP_DBG_ON
#define IP_REASS_DEBUG LWIP_DBG_ON
#define MEM_DEBUG LWIP_DBG_ON
#define MEMP_DEBUG LWIP_DBG_ON
#define TCP_DEBUG
I made some futher research and observed that in local network that
fragmented page worked only on one computer. On every other one the page
was not loaded. It was caused by "Content-length" field in http
header.After I deleted that line, page was loading on every PC on LAN, but
still not on 3G.

Today I finally updated my lwip to 1.4.1 and now it works. Release 1.4.1
contained many changes in tcp code and it seems that one of them fixed my
problem.
