sub domains

[BobbyBudds]

Here is what I want to do, on my splash screen I have 2 options Canada and USA. If the person click the USA one i want it to go to www.us.sitename.com and if they click canada go to www.can.sitename.com. I think i might need to do it in the httpd.conf file but not sure exactly how to go about it. Also I was wondering if i could set this up for localhost? Thanks in advance.

If you have the subdomains allready set up then all you need is.
<a href="http://www.us.sitename.com">USA</a>
<a href="http://www.can.sitename.com">Canada</a>

Or am I misunderstanding what you are trying to do?
