I,
First I think that if two clients send the same request to a server,
the server should send the same answer. That's why I was looking at
the client requests.
I tried java web start 1.5 and java web start 1.6, guess what ? It is
working with java 1.5.
I read all the traffic, the server response are exactly the same, and
the only difference is in the client request to squid

 Cache-Control: no-cache

in the java 1.6 request.

Is there any way to override the cache-control, though my
"ignore-no-cache" does not seem to work ?

I will try with squid 3 (I currently used 2.6 STABLE )

Thank you for your answers.
