Where are the web files for the server IP stored? For example, if I go to 10.10.10.1, it loads the standard Welcome Page. If my first client modifies their site, and then I go back to the IP, it loads the first client's page. If a second client is then added, the IP loads their Welcome page. I'd like to associate the IP with a specific web page.
Apache uses the first website that uses a specific IP address when you access the server by IP. The only thing you can do is to create a default vhost for this IP address manually.
