Hi Peter, using TCPMON I can see that the server receives twice all the client requests. The first immediately and the second after few seconds. It is very strange, because the HTML code is quite simple and with other AppServers like Websphere the problem doesn't exists. So I think about some possible configuration problem with JBOSS. if you have any ideas.. tnx! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977214#...
