Loading screen for servers

How do I make a loading screen for servers? Well I have the loading screen of course but how do I upload it?

You can use Dropbox, but for things like .php Webpages, you gonna need a server hoster.

I think there is a command to change the loading page, ‘loadingurl’?

sv_loadingurl http://yourwebsite.com/loading.html or whatever your loading URL is.
