RE: From which apache virtual host did a request come from?

Hrmm...   or not...
 
It must be an Apache setting, but hopefully someone here will know it.

If I specify something like this:

<VirtualHost 255.255.255.255>
     ServerName myfoo.com
     ServerAlias blah.myfoo.com
     ServerAias xyz.myfoo.com
     ServerAlias abc.myfoo.com
     DocumentRoot /home/webhome/myfoo
     #deny WEB-INF
     <Location "/WEB-INF">
         AllowOverride None
         deny from all
     </Location>
     JkMount /* tomcat1
     ErrorLog /var/log/myfoo/error_log
     CustomLog /var/log/myfoo/access_log combined
</VirtualHost>

Then within Tomcat, request.getServerName() always returns "myfoo.com"

If I separate each and every VirtualHost, then of course it works fine.
So blah, xyz and abc would all have their own VirtualHost, as opposed to
ServerAlias(es? ii? um?) Is there a way to get Apache to forward along
the requested AliasName as the ServerName ?
