Hi,
You could also do this with just one squid instance listening on just
one
IP address.
Let's say that your domain is www.yourdomain.com.
On your firewall you route the traffic coming to the public IP that
corresponds to
your domin to the IP of your squid box (which is listening on port 80).
By using a redirector you can separate the three servers;
www.yourdomain.com/site1 would be the 172.16.0.2:80 and we call it
server1
www.yourdomain.com/site2 would be the 172.16.0.3:80 and we call it
server2
www.yourdomain.com/site3 would be the 172.16.0.4:80 and we call it
server3
So in your redirector you configure something like (this is the format
SquidGuard uses):
[EMAIL PROTECTED]://www.yourdomain.com/[EMAIL PROTECTED]://server1:[EMAIL
PROTECTED]
[EMAIL PROTECTED]://www.yourdomain.com/[EMAIL PROTECTED]://server2:[EMAIL
PROTECTED]
[EMAIL PROTECTED]://www.yourdomain.com/[EMAIL PROTECTED]://server3:[EMAIL
PROTECTED]
As you can see, the www.yourdomain.com/site# transforms to server#.
You have to have corresponding entries in your /etc/host for your
servers.
If you need more help setting up something like this, don't hesitate to
ask.
Kind regards,
Tuukka
