Very odd. Why would your web servers act differently depending on how
the DNS is registered? My only guess is that the session data isn't
replicated proper.

When using Squid the requests gets distributed among both servers, even
if from the same client.

Then using direct connection the client resolves the IP once and then
generally sticks to that IP for the session (or at least until error).
