Unlike the GFW, the GC only acts on the first data packet of a connection
不同于GFW，巨炮只对连接的第一个数据包采取行动
For a given source IP address and port, the GC only examines the first data packet sent when deciding whether to inject a reply. To avoid examining subsequent packets requires remembering which connections it has examined in a flow cache. Unlike the GFW, the GC does not reassemble packets, a significant implementation difference. In addition, the GC will process invalid HTTP requests, while the GFW will not, also indicating differing implementations.
对 于一个给定的源IP地址和端口，巨炮只检查第一个发送的数据包以决定是否注入一个回复。这是为了避免在检查按顺序发送的包时不得不记忆哪些连接是已经检查 过的（也就是在流缓存里的）。不同于GFW，巨炮不重组包，这是一个显著的实现差异。补充说明，巨炮会处理无效HTTP请求，而GFW不会，这也意味着不 同的实现。
