[Users] moved temporarily - different port, same host

[Benko]

Hello!

Thanks for the fast answer. No, proxydomain.org points to
2xx.xxx.xxx.x06 which is the openser-host, 6x.xxx.xxx.x93 is the user
agent. Is the reply from the UA wrong, should it contain it's own ip as
redirect-contact?

regards
Christian
