I'm new to Varnish, and I'm hoping it already does this "out of the box", but I'd like to clarify before I consider using it in production:

Here's my setup:

1. I have multiple sites running off of the same machine that vary by subdomain (i.e. user1.example.com, user2.example.com, etc.)
2. Each "site" has a profile picture that has the same name (i.e. user1.example.com/profile.png, user2.example.com/profile.png)

Will Varnish recognize these as separate resources and cache them accordingly? Or will I need to change something in the VCL to tell it include the full host url when looking up cache hits?
