A couple of simple questions...

[Skye Poier Nott]

Hello... a few beginner questions:

1. When you restart Varnish the cache is always purged?

2. If I have a section like this in vcl_fetch, is the default_ttl  
parameter basically ignored? (assuming default_ttl is less than the  
value below).  So in other words, this VCL code enforces a minimum TTL?

	if (obj.ttl < 36h) {
		set obj.ttl = 36h;
	}

3. When I want to use Varnish in a WAN transparent accelerator mode,  
if I don't specify any "backend default" is the default to fetch the  
document from the hostname in the URL?

Thanks,
Skye
