How to make a virtual host?

[H.Päiväniemi]

Hi,

I'm a varnish-newbie.

How on the earth can I make a virtual host in varnish?

I would like to, for example:

* make a default virtual host with a backend A

* make a virtual host "host1.foo.bar" with a backend B

* make a virtual host "host2.foo.bar" with a backend C

...and of course there would be different caching rules in all of those.

But how?

Thanks,
