That depends on what web server you're using, and how it supports multiple 
domain names.
For example, Apache can support multiple virtual hosts all pointing to the 
same IP address - it distinguishes what virtual server to use by using the 
"Host:" header in the HTTP request. In this case, you just have one plug 
and let the web server distinguish.
Microsoft IIS, however, requires that you use different IP addresses or 
different port numbers to distinguish between virtual hosts. In that case, 
you run multiple plug-gw's on the outside that plug to the virtual targets 
on the inside. The plug-gw's on the outside can either bind to different IP 
addresses (assuming you've got the ipbind patch) or different port numbers 
on the outside, each of which point to different internal servers.
