I noticed that this is not a POST MANUAL WND problem but a general problem with receiving more data (both GET and POST). As I increased TCP WND from #define TCP_WND (2 * TCP_MSS) to #define TCP_WND (8 * TCP_MSS) I can receive more data before the problem occurs. But the problem still occurs when I want to send a larger file, it looks like the automatic TCP_WND control does not work for https. I attach the screenshot from wireshark as it looks. https://drive.google.com/open?id=0B6fxdAbp613KeTV2Z05rU2xNSUZoOEF2MF9xTWMxdHVJZUE4 -- regards tomek _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
