Do you have any idea how to make squid use that header?

I don't think we're doing anything special to make it happen. Here are the headers from a couple of typical transaction, with a few host names slightly obscured. This is using my own Java-based caching code on top of httpclient alpha 1. (I'm starting to upgrade to the latest version now).

Try to fetch a resource from a machine the Squid proxy doesn't have access to:
