Brain glitch: how to get environment server name (not ip)

I'm having a brain glitch, so this may be a dumb question, but here goes. How would you create "Send To a Friend" hyperlink in an application with both intranet and internet users?

I thought of using CGI variables
http://#CGI.SERVER_NAME#/SomePage.cfm?id=89

But as I understand it CGI.SERVER_NAME will return an IP for intranet users accessing the site via a private IP address. So the result would be link containing a private IP address that's meaningless to the outside world.
http://192.168.x.x/SomePage.cfm?id=89

Is there any way around this aside from hard-coding?

CGI.HTTP_HOST will return whatever the URL has as the server host... so if the url uses an IP, then that is what you get.

Darn. I was hoping there was a way to get the server name without hardcoding. Though now that I think about it, I guess that wouldn't be possible. I mean if more than one name was mapped to a single IP, how would CGI know which one to return?

IIRC cgi.server_name is going to return the server actually running the
application. I think what you are asking about is cgi.referrer?
