Re: [squid-users] reverse proxy, 2 backends and vhost

 Thanks Henrik, but I have more than 100 000 subdomains on 'mysite.com',
and new sudomains are added each minute. I can't list all domains and I
don't want to edit /etc/host every time a change occured. It seems to me
that wildcard (*.mysite.com) doesn't work in /etc/host .

I only want that one subdmain (storage.mysite.com) goes to another backend .

/etc/hosts is fine.. my recommended method for telling Squid-2.5
accelerators the address of the real web server(s).

Squid.conf accel settings:

httpd_accel_host your.main.site
httpd_accel_uses_host_header on
httpd_accel_port 80

Squid.conf access controls (inserted where instructed, with the defaults
kept)

acl mysites dstdomain your.main.site other.accel.site etc..
acl http protocol http
acl port80 port 80
http_access allow http port80 mysites

List the servers and their sites in /etc/hosts

In 2.6 the setup is simplified a bit, no longer needing /etc/hosts.

Henrik
