The problem with that is the 3 IPs need to proxy for 3 different web servers (3 IPs). -----Original Message----- From: Jerry Thomas [mailto:thomasj@xxxxxxxxxxxxxx] Sent: Wednesday, August 31, 2005 1:55 PM To: Brad Taylor Cc: Squid Users Subject: RE: Reverse Proxy Multiple IP Addresses Hi Brad, I am a little confused it sounds like you are just try to put a squid server in front of 3 apache servers. I guess they used to be LB'd somehow. When I said: Configure the squid server to listen to the 3 ips, I meant to set up ip aliasing on the particular ethernet interface. Then just set http_port to 80. This will be incredibly more efficient than running 3 squids processes. >From my personal experience I had 8 dedicated apache servers running a cluster. I was able to get it down to 2 servers running a custom compiled squid and two apache backend servers. I had to have the second apache in case of issues but they were both lightly loaded. Hopefully you will be able to do the same.
