Sorry for that. > > Juliusz I agree with you 100% that whatever client doing the half close socket is silly. However, when the offending client is Microsoft Media Player. Ignore the issue might not be a good idea either. Besides, the RFC 2616 leave the handling of half close socket to http server. The server can close immediate upon receiving the FIN, or the server can choose to handle a half close connection. But it is not clear if proxy can make such a decide on behalf of the server. These stream video server seems to think that half-close connection is OK to them.
