vhost?

["Jen mlists" <practicalperl@xxxxxxxxx>]

hello list,

I saw this statement on ReverseProxy wiki:

If you are using Squid has an accelerator for a domain based virtual
host system then you need to additionally specify the vhost option to
http_port

http_port 80 accel defaultsite=your.main.website vhost



When using vhost,does it mean squid act as a domain based vitual
host,or real server was a domain based vitual host?

Thanks!
