RE: [squid-users] Using squid 2.4 as an accelerator

Any help on the following? I don't see in the Squid documentation where they
go over all of the details of setting up IP-based virtual hosting with
Squid. The docs only get so far as "httpd_accel_host virtual" and then
pretty much drop it.

So I setup the IP aliases on the Squid box. But how do I tell Squid which
web servers behind it to use? We want to spread the accesses over n
webservers.

Any help would be appreciated, thanks.

Regards, Dustin
