[Serusers] ERROR on Request line ACKNOWLEDGE

Thu Sep 2 19:09:21 CEST 2004

Both of them are correct. In the first ACK the user agent correctly
recognized that the next proxy server is loose router and put the
Contact from 200 OK into the Request-URI of ACK.

In the other example, the user agent did not recognized that the proxy
is loose router (or does not implement loose routing) and behaves a
specificied in RFC2543, it puts the content of the Route header field
into the Request-URI and the Contact from 200 OK is put into another
Route header field.

Both cases should work.
