Hi,

I am using Squid3 nightly built 20071026 running on Ubuntu 6.06 LTS with the compilation options :-

./configure --with-pthreads --enable-icap-client

I tried both (i) the configurations with default option, or (ii) icap-enabled options, the Windows client failed to get WindowsUpdate (see the following log).


Where is this failure you speak of?
The log you posted showed a proper link to WindowsUpdate, with all the static content coming from cache (TCP_HIT/TCP_IMS_HIT) and the dynamic pages and updates being brought in from M$ (TCP_MISS)

If your client got the custom M$ "Windows Update failed" page.
Then I suspect you have overlooked a M$ nasty:
  WU requires an HTTPS 'validation' test.
  You MUST permit an HTTP 'CONNECT' request to 65.55.184.125:443.
(the IPA being that of www.update.microsoft.com from your current location)

This bypass needs to be made on your firewall. WU will NOT always attempt it through the configured proxy :-(

The best you can do is bypass it at the FW and also configure the proxy manually in IE, then run "proxycfg -u" in command line on the windows box, and hope that the particular box update level will use the proxy for it.
