mac osx - Can I specify a port in an entry in my /etc/hosts on OS X?

I want to trick my browser into going to localhost:3000 instead of xyz.com. I went into /etc/hosts on OS X 10.5 and added the following entry:

127.0.0.1:3000 xyz.com

That does not work but without specifying the port the trick works. Is there a way to do this specifying the port?

Answer

No, the hosts file is simply a way to statically resolve names when no DNS server is present.
