It's good to hear that this will be addressed in the next update. My Wireshark log tells me, that the 304 stuff if not done for me. That would make sense since the Expires header is set to the past (same as the Last-modified). Even worse is that for every single resource a new TCP connection has to be openend. I'd guess the TCP handshake takes even longer than retransmitting the small resources. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4143653#...
