IE doesn't resolve for the first time

Hello,

I'm using squid-2.4 with PAM auth for my network.
Authorization works fine with IE and Netscape but
after authorization in IE I get "The page cannot be
desplayed"
and "TCP_DENIED/407" in my access log. If I reload or
visit other pages work well.
PS: With Netscape works well, I don't have that
problem.

I tried adding and removing resolv.conf form my conf
file, I've changed the DNS servers on my pc.


Any ideeas? 

Squid log:

1049037536.420      4 192.168.0.22 TCP_DENIED/407 1342
GET http://www.directnet.ro/ - NONE/- -

GET http://www.directnet.ro/ fredi NONE/- text/html

Squid.conf with pam_auth:

acl all src 0.0.0.0/0.0.0.0
acl password proxy_auth REQUIRED
acl HQLAN src 192.168.0.0/255.255.255.0
