Proxy Access to my Squid Proxy

  • 772

I have a squid proxy cluster to let my users surf in the internet and on intranet ressources.

Now there is a special user, that wants to configure another squid in the net of the users. So this proxy wants to access the internet over a proxy-proxy configuration.

It doesnt work at the moment.

So here is the question: Whats the configuration line for my squid.conf to allow an IP to use my squid as an upstream proxy?

proxy squid http-proxy

    Let's say you have two proxies:

     ________       _________       _________       __________
| client | --> | proxy B | --> | proxy A | --> { internet }
|________|     |_________|     |_________|     {__________}
              port           port
              8000           8080

    Your configuration for proxy A already works so we'll ignore that for now. The difference is that proxy B must be configured to send all requests to a proxy, not the internet. So how do to this in Squid for proxy B's configuration?

    Investigate the cache_peer configuration directive.

    Something like (for proxy B):

    http_port 8000
cache_peer proxy_A parent 8080 0 no-query

  2. On one proxy (the client side), you need to define the cache_peer.

    On the other proxy (the server side), you need to define the appropriate acl line to allow the proxy IP to use this proxy.
