mod_perl 2: $r->get_server_port returns wrong value

[Matisse Enzer]

Is it possible that the value returned by $r->get_server_port could 
be affected by the format or content of the client request?

I've got a test case where when i hit the same URL from two different clients
I get different values from $r->get_server_port.
This doesn't make sense to me, because I had believed that 
get_server_port gets its information from the server side only, but 
perhaps i am mistaken about that.
