I think that Pound is more suitable for what you are trying to achieve.
Although I don't know if Pound can handle a 1000 domain/backend
combinations.
No matter what you throw at it, 1000 stays a large number.

I suspect what I am trying to do here falls outside of Varnish's

Instead of using Varnish to cache content for a single site with
several backends, I want to use it to allow me to serve existing
sites on different domains.
For example I can run varnish on test.com <http://test.com> and serve
content from example.com <http://example.com> using this configuration.
backend test {
.host = "example.com <http://example.com>";
.port = "80";
}
sub vcl_recv {
set req.http.host = "example.com <http://example.com>";
set req.backend = test;
return(pass);
}
But what if I have 1000s of backends and I choose them based on the
domain that user's hit varnish with. Is this something Varnish
handles or is it only intended to work with a handful of backends?
Also, it would be really cool if I could do something like this..
sub vcl_recv {
set req.http.host = "example.com <http://example.com>";
set req.backend.host = req.http.host;
return(pass);
}
I'm guessing backends are defined ahead of time for connection pooling
but maybe not.
Anyway, this is long enough, tell me if I would be nuts to try to do
this with Varnish and if so what would be better. I'm tempted to
write my own proxy but that seems like such a waste. :-)
