How can't I understand several minor issues with the running code.

See

   draft-ohta-urlsrv-00.txt

   DNS SRV RRs of a domain implicitly specify servers and port numbers
   corresponding to the domain.

   By combining URLs and SRV RRs, no port numbers have to be specified
   explicitly in URLs, even if non-default port numbers are used, which
   makes URLs more concise for port based virtual and real hosting,
   where port based real hosting means that multiple servers sharing an
   IP address are distinguished by port numbers to give service for
   different URLs, which is the case for port forwarded servers behind
   NAT and servers with realm specific IP.
