This was marked as TODO in the code: -Enable use of wget_with_dns even if CMD_DNS is disabled if the given uri has the ip address for the http server. -Check for port in the uri when transforming to legacy wget syntax inside wget_with_dns. -Move the check for CMD_DNS inside wget_with_dns.

Changes in v4 are not described:
* drop console output * avoid checking non-zero via '!= 0'.
v3: Removed console output inside efi routine.

RFC 1738 has:
login = [ user [ ":" password ] "@" ] hostport hostport = host [ ":" port ]
So here variable port may point to the password. And host_name to the user name. We might check for '@' and bail out with an error code if it occurs.
You are determining the host port as a string, but I cannot see where you are ever using it.
In wget_send_stored() I see this line:
server_port = env_get_ulong("httpdstp", 10, SERVER_PORT) & 0xffff;
Maybe make server_port a static variable and set it here if variable port does not contain a number.
