You can't do that with a packet filter - you need to use a proxy that 
understands the semantics of the HTTP protocol and can filter based 
on the site name rather than the IP address.

Doing what you have, the name will be resolved to an IP address at 
the time the firewall is (re)started and will allow packets destined 
to that IP address. Note that a server may host many (tens, hundreds, 
even thousands) different websites and the rule will allow requests 
to any of them. Also, many large sites have multiple servers and I'm 
not sure how that is handled by Shorewall.
