[squid-users] Wrong page got via squid

Hello squid-users,

On this site:
http://www.journal-officiel.gouv.fr

clicking on every "passer une annonce" gives, via squid, a page
"SITE EN COURS DE MAINTENANCE" (under construction or so...)

With direct connection, we are getting another, "good" version of
the same page:
http://boamp.journal-officiel.gouv.fr/

Maintainers suggest us to reinitialize our proxy (!)

In cache.log I see only:

1115368256.084 0 161.3.1.41 TCP_IMS_HIT/304 217 GET
http://boamp.journal-officiel.gouv.fr/ - NONE/- text/html
1115368256.102 0 161.3.1.41 TCP_IMS_HIT/304 221 GET
http://boamp.journal-officiel.gouv.fr/boamp-web-img/rub_fd.jpg - NONE/-

1115368256.106 0 161.3.1.41 TCP_IMS_HIT/304 219 GET
http://boamp.journal-officiel.gouv.fr/boamp-web-img/frise_gris.gif - NONE/-

I tried the cacheability engine on http://www.ircache.net/ for
http://boamp.journal-officiel.gouv.fr
The engine complains about an "inaccurate server's clock"...

Could I do something to get the correct page ?
Thanks for your suggestions,

squid -v
