Newbie squid / apache reverse proxy question

Hello

I am trying to setup squid2.5 on linux fedora 4 as a reverse proxy for
multiple domains on apache 2.2

This is part of my squid config file:

httpd_accel_host virtual

httpd_accel_port 8888 (apache port)

httpd_accel_single_host off

httpd_accel_uses_host_header on

however i am unsure of how to set the reverse proxy for the domains

Currently I get the following error when i enter the url http://site1/

The requested url could not be found

While trying to retrieve the URL: http://site1:8888

Unable to determine IP address from host name for site1

By putting the url http://192.168.10.111 it works
It also works if you put in the port number and bypass squid.

If anyone knows how to get squid to recognise site1 that would be a
great help.



Thanks
