... but on second thought, maybe it's not that much black magic after
all. The "main" object, which can be cached, can contain an ESI
include for a fragment that points to an application that just prints
out whatever it finds in X-Fowarded-For. Then you'd have to make sure
that the included fragment is never cached -- return(pass) for the
URL. (Can you do that with ESI?)

But still, without knowing what the problem to be solved is, I wonder
if this solution is overkill.
