That's correct on all servers : only one declaration and the good one.

No. Scripts generating DNS and hosts file check for duplicated
definitions. And there aren't. I also tried removing declarations of cg
at hosts file - to force cg.ensmp.fr resolution only by DNS - the result
is the same.

If I try, on the shell, to get into these servers (telnet cg.ensmp.fr
80) - I get connected without problem.

If I try the URL http://cg/, it works !

I also disabled nscd...

I found three different internal destinations with the same problem
(cg.ensmp.fr, cmm.ensmp.fr and cig.ensmp.fr).

On my workstation, I have no problem

I also asked for a friend of mine on a external domain to try to access
these servers, passing through a squid cache. It works fine.

Could it have some problem with internal resolver calls in this specific
situation : append_domain configured and accessing internal servers ?
