Start Bottle.app with Tornado server.

I have next config on my server:
nginx(listen port 80) >> tornado(listen 8888 port) >> bottleapp.
When tornado server started, default host(address) is "", and he listen all possible hostnames('localhost", ip on local network, ect) on port 8888
Wee can  go at our site like example.com/  and example.com:8888/ . It's not safe.
