First of all, take a look on: http://cppcms.com/wikipp/en/page/cppcms_1x_config#http.timeout You may want to increase this parameter. 2nd what kind of chat do you implement? Long polling or type of event-stream? Also the client should be ready for disconnections and restart connection. You can also send some kind of applicative keep-alive messages (not HTTP keep alive) so the client would know that the server is up.
