Whatever you want old HTTP/1.0 clients not sending Host headers to receive. If not set they will just get an "Invalid request" response.. > if without defaultsite, I have to set "always_direct allow all" The two is unrelated. Hmm.. not entirely sure how to best configure the accelerator mode to suit an CDN type setup with a large and dynamic number of backend servers. It's primarily designed for more restrictive environments with a limited number of backend servers, relying on a cache_peer definition per backend server. You can override this with always_direct, but then peering isn't possible. The reason to this is security, to ensure the accelerator isn't accidently configured as an open proxy. You can take away this restricion by commenting out/removing the accelerated test in peer_select.c. Peering in accelerator mode will then be equal to how things works in proxy mode which maybe is more suitable for your setup, assuming you use a private DNS structure with real web server addresses for the distributed sites.
