Two squid servers to talk to each other before the internet

[Tóth Tibor Péter <tibor.peter.toth@xxxxxx>]

I was wondering, if is there any way to get two squid servers to talk to each other before going out and cacheing data from the internet?

Here is what I would need to do:

             ┌────────┐
             │   INTERNET   │
             └────────┘
                     │
    ┌───────────────────┐
    │                                 │
    │                                 │
┌────┐                       ┌────┐
│SQUID01│<---- I NEED THIS ---->│SQUID02│
└────┘                       └────┘
    │                                 │
    │                                 │
┌────┐                       ┌────┐
│CLIENT1│                       │CLIENT2│
└────┘                       └────┘

I want SQUID01 and SQUID02 to "ask" each other if the other have the data, before going out to the web. I guess you call this exchanging data between squids? In case if one server go down, the other need to go directly to the internet, and not just standing and waiting for answer from a disabled machine.

Can this be done int he squid.conf file?

Thanks,
