I do now see the behavior which you described, but with the NIO connector: There the browser is the one which closes the connection (probably due to a data corruption). E.g. when redirecting IE and make it stop to read incoming data for ~ 30 seconds, then make it to continue reading, IE will display (translated from german): "SCRIPT12152: WebSocket Error: Network Error 12152, The server sent an invalid or unknown reply" and reset the TCP connection. When I tried this with FF, it first seemed that here Tomcat was the one which initiated a normal TCP shutdown, but on more debugging it seems that Firefox stopped at some point to process the received messages and then sent something like a Websocket Close message so that Tomcat closes the connection (when pausing the Firefox -> Tomcat connection prior to unpausing Tomcat -> Firefox direction, Tomcat continues to send data). When trying with APR, I keep seeing that Tomcat initates the connection shutdown. With BIO, the problems don't occur.
