I actually found this site because i was trying to get help, and the developer of the plugin seems cranky at the best of times. Basically the system works, updates that a PC doesnt have gets loaded from the firewall rather then the internet, but the updates themselves, it seems that MS use multiple servers to store each update, now when I update a SP2 XP pro system, it sees SP3, it downloaded a 850meg file, thats fine, it must be multilanguage versions that its downloading.. the problem is that i update another SP2 system and it starts downloading the 850 megs again as its got the same file name, but comming from a different server. would anyone here know how to rectify this? im a 100% noob at linux but i have managed to get it up and running without too much issue. here's the plugin website for those interested. http://update-accelerator.advproxy.net/ any help would be appreciated :) planetx...@gmail.com
[squid-users] Accessing attatchments in yahoo mail
I had a transparent squid proxy setup and was having issues where yahoo attachments after scanning and enabling the interface to download them would logout a user when clicking the link. Thinking this had something to do with the switching back and forth from http/https and being transparent, I setup the clients with a proxy and removed the redirect firewall rule and set squid to not be transparent. The problem still exists though and searching the net shows others with the same issues but I haven't found a solution yet. Thanks! jlc

The reason I set a one month expiration time on jpeg images in that directory is I don't expect the jpegs in that directory to change very frequently but when they DO change, I need Squid to refresh its cache as soon as that image is changed (or shortly after). What should I do to address this? Thanks! Peace... Tom Please ignore this post. I think I found my problem. The images I was changing were NOT in the above listed directory so something else is going on. Peace... Tom

Re: [squid-users] Native WIN32 NTLM and Basic Helpers must be used without the -A & -D switches.
Hi, At 10.46 19/12/2008, Paul Cocker wrote: Having noticed that squid is now shipping with an mswin_check_ad_group file (I don't recall this in 2.6) I'm working on moving our 2.7 config over to it. In the readme it says: "- Native WIN32 NTLM and Basic Helpers must be used without the -A & -D switches." Our mswin_check_lm_group line used -D as I recall there were lookup problems without it, however I want to check what this line means. What is considered a native WIN32 helper? -A isn't documented as a switch either. Certainly we're a 100% Windows domain. Can anyone clarify this line for me? You are mixing authentication helpers with external ACL helpers. -A & -D switches are only for mswin_auth and mswin_ntlm_auth helpers.
