In the RFC 2543 , route header contains all the proxies it needes to reach
and as and when it passes the one of the interim proxies it will delete the
request uri and replace the next one which it needs to pass so as to reach
the destination . In this way request uri will be changing . This is called
strict routing. In  loose routing(RFC 3261)request uri will be seperated
from the changing and request uri will always point to the destination.

Please correct me if iam wrong.

vlrk
