Re: Squid as reverse proxy

Ok, so you are going for alternative B, one IP for each accelerated
domain.

--- squid.conf ---

http_port 10.15.1.251:80
http_port 10.15.1.252:80
httpd_accel_host virtual
acl all src 0.0.0.0/0
acl accelerated_servers 10.15.1.11 10.15.1.22
http_access allow accelerated_servers
redirect_program /usr/local/squid/bin/accel_redirector.pl
cache_dir ....

--- accel_redirector.pl ---

#!/usr/bin/perl -p
BEGIN { $|=1; }
s%http://10.15.1.251\b%http://docs.mydomain.com% && next;
s%http://10.15.1.252\b%http://solve.mydomain.com% && next;

Ah.. sorry. I apparently forgot the $|=1 statement in my original post.
This is required for proper redirector operation.

--- Internet DNS ---

docs.mydomain.com. IN A 10.15.1.251
solve.mydomain.com. IN A 10.15.1.252

--- Local DNS ---

docs.mydomain.com. IN A 10.15.1.11
solve.mydomain.com. IN A 10.15.1.22

Local DNS can be avoided by using --disable-internal-dns and adding the
hosts to /etc/hosts. The requirement is that Squid should be able to
look up the real destination server using the domain name.

You could also write the redirector to redirect to the backend IP
addresses directly, and make sure the backend servers know their domain
name (not sure this is possible using MS IIS for example)
