Do they really? I would think squid just pipes a CONNECT request wihout
caching the contents, just like varnish does. I'm not quite sure about
that, though.

What I *think* you need to do is to rewrite the request URL so that it
contains the hostname.

An incoming request like this.

| GET /foo
| Host: example.com

should be passed to squid in this form:

| GET http://example.com/foo

In VCL:

set req.backend = squid;
if (req.url ~ "^/" && req.http.Host) {
	set req.url = "http://" req.http.Host req.url;
	unset req.http.Host;
}
