Running two services on port 80
I have a QNAP TS-459 Pro II that comes with an Apache webserver which runs on port 80.
I'd also like to run a small Sinatra app; also on port 80.
I'd like Apache to serve up
foo.example.com, but I'd like Sinatra to serve up
Is it possible to have both webservers running on the same port but only answer based on specific domain binding?
