[SR-Users] How to chain proxies with Route header and loose_route()

[Brandon Armstead]

Ivan,

   This is a very old reference.  Check for msg_apply_changes() or some
such function as that.  Route headers can be preloaded but does not
necessarily guarantee order, i.e. a proxy in the chain does not properly
loose_route or otherwise.
