Hi If one side perform a half-close, but some of the data it sends out were lost, will it still perform retransmission? For a http1.0 server, it typically closes the socket after it answers user's request. And if some of the data were lost, user application will be hung up. Can any one of you give me any suggestion? Thanks a lot, xwz - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
