Re: TCP RST on rapid data in NIO Connector
Hi Filip, Also I need to add something more: 1. After a lot of googling and forum researchs, I saw a few topics about that. I have tried them all. They made it a little bit stable. (especially these ones : http://markmail.org/message/5zs7qejpjy3vxhfy and http://www.nabble.com/Comet-servlet-synchronization-and-flush-problems-td13879322.html ) 2. I think that problem is about Tomcat's handling of raw socket. As far as I know tomcat is not so capable as Apache in handling buffers. I wanted to try comet over Apache but I could not complete it. Mod_jk does not support nio. Can you offer any methods about this? Thanks again..

TCP RST on rapid data in NIO Connector
