[squid-users] tcp_miss/502 when surfing with IE6 to http://www.raiffeiseninformatik.at

Hi,

We are currently having a strange problem with our Squids (3.1.9, on
RHEL 5.5 64Bit).

When we surf to the site http://www.raiffeiseninformatik.at with IE6,
we get a ERR_ZERO_SIZE_OBJECT error message. With every other browser
(tested FF 3.6.12 and Chrome 8) it is working without issues.

access.log-entries:
IE:

16761 GET http://www.raiffeiseninformatik.at/ USERNAME
DIRECT/217.13.189.96 text/html ICAP-X-Attribute:it

Does anyone have any ideas why it does not work? I compared both HTTP
requests (you can find them below), there are some differences, but is
that causing the problem? Maybe it is a strange IE6 client policy
option?

best regards
