[squid-users] A error with IE 6 and Proxy on one web site ...

Hi

i have a small problems with my Squid Proxy (NTLM Authentification) :

When i want going on the web site: http://www.ratp.fr, Internet Explorer
open a download box
with a file type "ratp" and never put me the web site ..

If:
 
1- I use Firefow with the proxy => No problems, i see the web site
2- I use Internet Explorer without the proxy => No Problems, i see the
web site
but if
3- I use Internet Explorer with squid proxy, i don't see the web see and
he want that i download the file ..

In my access.log, i don't have a big information:
1116432295.185 469 172.16.10.15 TCP_IMS_HIT/304 223 GET

1116433931.229 1 172.16.10.15 TCP_IMS_HIT/304 224 GET
http://www.ratp.fr/ borlotte NONE/- text/html

anyone have a idea ? can you see you this web site with your proxy ?

Thanks bye
