I get a 15min cacheable 302 response from that.

Are you perhapse looking at your logs with out query strings?
 That cacheable 302 I mentioned redirects to itself with lots of extra
CMS query string parameters.


Following that redirect dumps out a program binary with "Vary: *" which
changes per request. If you look at the chrome installer itself the
application binary contains per-user embeded code and "stuff". So no its
not cacheable.


The only cacheable part of this is the 302 response.
