I have a question about redirecting a subdomain of a blog hosted on wordpress.com to an external URL.
Given the following:
1) I own a domain name foobar.com purchased from another registrar (not from wordpress.com).
2) I have purchased the custom domain option on wordpress.com, and have completed the configuration to make foobar.com resolve to foobar.wordpress.com.
3) I will establish an external site for a store, such as store.yahoo.com/foobar.
4) I want to redirect the subdomain store.foobar.com to store.yahoo.com/foobar.
How do I set up the custom DNS records within wordpress.com to accomplish this subdomain redirection, while leaving foobar.com pointed to my Wordpress blog? I suspect that the CNAME directive is involved, but I cannot figure out the required syntax.
