[TYPO3-english] Menu links for subdomains

[Sergio Catalá Gil]

I use a different "config.baseURL" for every subdomain on my site and
eveything works ok. The problem is: I want to use the same menu
structure and links for the items of the menu as the main domain. As I
use "config.baseURL", <base> tag in the header changes automatically and
all links point to the subdomain.   

Is there a way to use the original links (main domain) in HMENU? I
didn't see anything on TSREF.

Thanks in advance, 
Sergio
