[plug] Apache Server Alias

[skribe productions]

Hey folks:

Currently my serveralias is set to *.myname.com serving as a catchall
for my web site.  I'd like to be able to have some files hosted
offsite, but still use something like media.myname.com.  I've set up
the appropriate cname in my dns but apache keeps serving up the
website rather than the offsite.  Is there a way to do something like
a regexp in serveralias to enable me to do both catchall plus offsite
address?
