I found when making requests the log pops a lot logs like or similar to the following:
2020-03-27 14:06:10.966089+0800
ProjectC[20844:8100184] [] tcp_input [C23:3] flags=[R] seq=3301246612, ack=0, win=0 state=LAST_ACK rcv_nxt=3301246612, snd_una=3639195287
However I don`t understand what these things mean, could anyone explain a little bit?
