RE: [squid-users] squid3 WindowsUpdate failed

Hi all..

I know that this is not the answer that you are looking for, but why not
just install a WSUS server internally? Then point all your clients to it
via AD policy. (me being a lazy bugger here!)

Lucky you, looks like you have a good up-to-date user base then :). Mine
have trouble in WinXP SP1 and some earlier versions of the ActiveX WU'er
they call MicrosoftUpdate. GenuineAdvantage my a*%#.

IIRC others earlier found that WU used range requests to speed downloads.
I have never confirmed this myself.

Anyway, a bug has just been found in 3.0.RC1 that caused certain range
requests to close prematurely.
http://www.squid-cache.org/bugs/show_bug.cgi?id=2116

A fix has been incorporated in the next daily snapshot. If anyone is
having this problem with 3.0.RC1, please give the 31 Oct or later
snapshots a try and see if that fixes your problem.
If its still present it will need to be reported as a bug with traces,
etc.
Thank you.

Amos
