Actually HTTP sessions >> effective users, since each user has a 10 minutes simulated navigation but the HTTP session is lasting a lot more (I think 1 hour by default in tomcat). What I thought was that using HTTP 1.1, I would have only 1 phisical connection to the server for each user... This seems not to be, as if the same physical connection is used contemporarily by more clients. I am asking if it could be a poor testing design or if we are wrong in our consideration... > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org > For additional commands, e-mail: users-h...@tomcat.apache.org > > >
