原文摘录

摘自原文(5512 字符中的一小部分)
Summary: I have discovered a logic flaw in lib/ws.c regarding the handling of WebSocket Control Frames (PING/PONG). According to RFC 6455, Control Frames should be processed as soon as possible, even in the middle of fragmented data frames, to maintain connection state (Keep-Alive).
