Individual Cache for different Browsers?

[Josh]

My guess is that it's the cookies you're sending through.  I had the
same problem and it turned out to be analytics cookies.

Those _ut* cookies look like the same thing.  You can strip those out
using something like this in vcl_recv

set req.http.Cookie = regsuball(req.http.Cookie,
"(^|;\s*)(__utma|__utms|etc...)=[^;]+;?", "");

and that should take care of it.
