Squid accelerator mode

> Hi,
>
> I have question about accelerator mode in Squid. It's written in the
> documentation than when Squid is in accelerator mode it fetches
> documents from one or more origin servers.
>
> I need to achieve solution, when user sends http request to machine A,
> which has some cache. If the requested page is not in cache, machine
> will send a request to one of the set of http servers (!!!), then it
> handles the answer, stores it in cache (if needed) and resends to a
> client. The IP packet should have source address of machine A (the
> solution is transparent to client).
>
> It's very important that in case of some http server are down, Squid
> won't redirect http request to these servers or in some way get the
> answer from other (alive, if any) http server.

> As far as I know it can be configured using Squid accelerator mode, but:
> 1. Is it configured using httpd_accel_host multiple times in squid.conf
> file?
> ex.
> httpd_accel_host IP_A
> httpd_accel_host IP_B
> ....
> httpd_accel_port 80
>
> 2. If it is true, how Squid selects real origin http server from the
> above list? Using round-robin procedure? And what happens if one of them
> goes down. Is there a possibility that Squid will "omit" that server?

> If it's not possible to solve using Squid software, maybe you can help
> me in finding an appropriate one.

> Thank you very much for an answer and help in advance
