Verify the agent is utilizing the proxy. The Patch Agent Control Panel displays the proxy it is using if it is assigned. And using an ACL means you can have different values for different purposes, but also means that you do not need to change the overall system default behaviour that allows squid to handle ranged downloads, just to force caching of windows updates.
Which then causes other problems with content that should be chunked but instead squid is downloading full files. Not bad with small files, but with very large files, squid will appear to be unresponsive and possibly even slow down performance wise as squid is trying to download multiple large files that should have been chunks of a file until it can get a copy into it's cache.
And of course, this applies to any traffic whereby you want to override the default chunk download behaviour, but don't want to force for all traffic. And further, that these statements will appear in the generated squid. So if you're having problems with squid misbehaving with chunked downloads, check your squid.
If people want to abuse Squid for nonsense like distributing Windows updates, they need to do it manually. There's also some crap like Avast I know for fact it's completely no-op, they've switched to streaming updates that occur hundreds times every day , or Symantec - exactly the same.

Run a nameserver on the firewall or use an internal nameserver. Security - X-Forwarded-For When a proxy-cache is used, a server does not see the connection coming from the originating client.
Many people like to implement access controls based on the client address. We must note that access controls based on this header are extremely weak and simple to fake. Anyone may hand-enter a request with any IP address whatsoever. Because of the weakness of this header, access controls based on X-Forwarded-For are not used by default.
Yes it can, however the way of doing it has changed from earlier versions of squid. Please follow the instructions for the version of squid that you are using.
As a default, no anonymizing is done. NP: Squid must be built with the --enable-http-violations configure option before building.

Improve this answer. Thanks for the information! That is crazy, given that the ordering you had and which I had too comes from the default squid3. I wonder if the squid developers are going to fix this either the ordering in the default config file, or making this work in any order Sign up or log in Sign up using Google.
