Re: Squid accelarator for many web servers

What you need to do is to

1. Write a redirector that rewrites http://ip-server-X/ to
2. move each server to a new address
3. set up a virtual interface on the squid server for each www server
(with the official adress of the server)
4. use http_accel virtual 80

Or you could use the Host: model...

1. use http_accel main-server 80
        http_accel_uses_host_header on
2. Write a redirector that rewrites http://server1.../ to
3. Give the squid server the names of all servers it accelerates (moving
the servers to different internal names).

It is hard to do it without changing the condfiguration of your server
machines or DNS, but since you have control of your router it might be
possible to use transparent proxying to accelerate the servers...
