That's kinda weird. One (unlikely) possibility would be that the server responds differently when it does not see its port in the request. Could you force it to see if it changes anything : curl -H "Host: localhost" http://localhost:7000/ curl -H "Host: localhost:7000" http://localhost/ > I've also included the lsof results and hosts file on web01, everything is > the same on web02.

You don't even have "option httpclose", so that means that the connection passes unmodified. Please run it in debug mode if you can (using -d) and check the output for request/responses. Maybe we'll see something odd, but I have no idea what. Also you could try to switch to "mode tcp" and see if that changes anything. If so, that means that it blocks in the HTTP protocol. If it does not work either, then it will be more likely a problem handling the Host header. Regards, Willy
