subdomain-based page caching?

Hello,

I just wanted to verify my understanding; As of rails 1.2, it was impossible to have independent page caches on a per-domain basis, right? In other words, if a single rails app responds to both http://foo.com/index.html and http://bar.com/index.html, and uses page caching, it *must* deliver the same page from cache for both of these requests.

I'm assuming this b/c cached pages supposedly never invoke your rails code, so there is never an opportunity for your app to differentiate the location of the cached files based on the domain.

Is this understanding correct? Or is there a way to get http://foo.com/index.html and http://bar.com/index.html to be page-cached independently?

If not for Rails 1.2, then how about for any newer versions? I'm not up to date on the 2.x capabilities.

Thanks,
Avram
