/etc/hosts is fine.. my recommended method for telling Squid-2.5
accelerators the address of the real web server(s).

Squid.conf accel settings:

  httpd_accel_host your.main.site
  httpd_accel_uses_host_header on
  httpd_accel_port 80

Squid.conf access controls (inserted where instructed, with the defaults
kept)

  acl mysites dstdomain your.main.site other.accel.site etc..
  acl http protocol http
  acl port80 port 80
  http_access allow http port80 mysites

List the servers and their sites in /etc/hosts

In 2.6 the setup is simplified a bit, no longer needing /etc/hosts.
