klaus,

yes, but the two via test tells that ua is not taking directly to this
sr instance and i thus don't need to care about it.

i first thought to add the $du test, but looks like the via test makes
it unnecessary.  however, loose_route() may be key to solving the reply
problem:  if loose_route() sets $du, it means that next hop is another
proxy.  then it is possible to set TO_PROXY flag and test it
onreply_route.  right?
