1. Why not do that, then?
2. Have you considered using Apache in reverse-proxy mode instead of Squid?
It will happily re-write headers for you, and also supports load balancing
around multiple servers, which would possibly give you a high-availability
solution as well.

1. Because when you have a normal cdn bought from commercial parties, you don't add a cdn.example.com vhost alias into your configuration ;) It's just not right. The cdn should be transparent.
2. Squid allows to create a hierarchy of caches (mesh) and can cache in memory - these are the reasons not to use Apache/Nginx in my case. Yes, you can use a distributed file system, but that's an extra layer. And yes, Apache can cache to disk and OS will cache into RAM. It seems squid + ICP + mesh is just fine for what I need.
