How Mirror sites are made?

[Peter65]

I have a doubt in my mind, how Mirror websites are made & automatically updated when they edit the content in one server it changes in all the places simultaneoulsy.

Can some experts here explain it?

LOL, I don't know how people update their mirror sites.

But, as you know, it's very easy to just upload your pages on several different host when you make changes. Of course, you need php so, that your pages layout and contents are easy to manage :p
