Well, at least with 2.0, that's the way ServerName is documented...
nd is right... the actual physical port can never be, afaik, 0, so wherever that is in the logic path, that's the final end :)
But on thinking it even more deeply, having Apache return the physical port can always be done via setting it explicitly in ServerName (for 2.x) or adding a Port directive to the <VirtualHost> tag for 1.3... Many people may not be aware that:
Port 8080 <VirtualHost 10.0.0.1> ServerName foo Port 80 </VirtualHost>
is possible and legal in 1.3 and makes the Vhost return foo:80 with UCN On and, with UCN Off will force Apache to set the port to 80 if the client doesn't add one to Host. So if with UCN Off they want the physical port to be sent, ensure the value for Port is whatever the actual listening port is; if they want some other port, then it can be set. But it doesn't cause the Vhost to actually *do* anything on port 80.

I guess the part that confuses me most is why is honoring the physical
port number a bad thing? If you look at the implementation of
ap_get_server_port() in the 2.0 branch, the function determines the port
value by:
USE_CANONICAL_NAME_OFF || USE_CANONICAL_NAME_DNS 1- parsed_uri.port 2- server->port 3- ap_default_port()
USE_CANONICAL_NAME_ON 1- server->port 2- local_addr->port 3- ap_default_port()
Notice that in the USE_CANONICAL_NAME_ON it checks the physical port
before calling ap_default_port() but USE_CANONICAL_NAME_OFF || DNS
doesn't. Shouldn't the sources of port information be the same for both
cases, just a different order? The patch in the 2.1 branch just fixes
this. But, it was pointed out by nd that if the local_addr->port could
never be 0 then the call to ap_default_port() is dead code and would
never be called. But if it could be 0 then what is the difference
between no port and a valid port value of 0. This is the reason why the
backport proposal has stagnated in the STATUS file. I don't know what
the correct answer is but I do believe that honoring the physical port
number is a good thing and should be checked somehow.
