    Someone asks I can help you understand where I'm wrong?

    Trying to use squid to cache Windows Updates.  You're better off running WSUS.

    You need  rewriter helper.  add this to config of squid.

    acl getmethod method GET
    acl dontrewrite url_regex redbot.org
    always_direct allow !getmethod

    store_id_access deny connect
    store_id_access deny !getmethod
    store_id_access deny dontrewrite
    store_id_access allow all
    store_id_program '/usr/local/libexec/squid/storeid_file_rewrite'  /path/to/db_file  # Searcch google how to use storeid_file_rewrite it is included in squid 3.5.19
    store_id_children 25 startup=15 idle=5 concurrency=0

    add that to squid config. that should cache most cdn but  it's a db base just google you will be able to find some db example in the web.
    store_id_rewrite:

    [code]#!/usr/local/bin/perl

=head1 NAME

 storeid_file_rewrite - File based Store-ID helper for Squid

=head1 SYNOPSIS

 storeid_file_rewrite filepath

=head1 DESCRIPTION

This program acts as a store_id helper program, rewriting URLs passed
by Squid into storage-ids that can be used to achieve better caching
for websites that use different URLs for the same content.

It takes a text file with two tab separated columns.
Column 1: Regular expression to match against the URL
Column 2: Rewrite rule to generate a Store-ID
Eg:
^http:\/\/[^\.]+\.dl\.sourceforge\.net\/(.*)	http://dl.sourceforge.net.squid.internal/$1

Rewrite rules are matched in the same order as they appear in the rules file.
So for best performance, sort it in order of frequency of occurrence.

This program will automatically detect the existence of a concurrecy channel-ID and adjust appropriately.
It may be used with any value 0 or above for the store_id_children concurrency= parameter.

=head1 OPTIONS

The only command line parameter this helper takes is the regex rules file name.
