[squid-users] windows update not working squid 3.5.2

Hey Ahmad,

 

Try the new version of ms-updates from:

http://ngtech.co.il/ms-updates-store/

http://www1.ngtech.co.il/wpe/?page_id=301

 

Since you are using an armX based system.

>From my point of view on things I do not see the difference between other traffic to MS updates.

Windows Updates are HTTP requests and responses which are identical to other objects.

When a proxy or a service starts to see these things with "new" perspective my assumption is that something with either RAM or CPU or DISK is wrong and couple simple objects will clear out things about the proxy state.


What I need is a testing use case from the squid world jargon.

Are you using an Intercept proxy?

If so what type of Interception? Tproxy or Intercept?

What objects did you tried until now? Only Windows Updates?

Do you have a dump of these requests?(you can use http://wiki.squid-cache.org/KnowledgeBase/DebugSections)

The dumps should be using section 11 ie: debug_options ALL,1 11,6

With these dumps we need the corresponding access.log.

These should be enough to think about things and maybe re-test them.

Also What OS are you using?

 

Eliezer
