Need software that allows same content on multiple servers
 

Anyone here know of any software or a solution available that will allow you to have the same content displayed on all web servers and sites? I have 3 webservers that I want to run my sites on and I want each of the sites to have the same content at any given time. So if a user visits the site they'll hit whatever server that's closest to them get the same content. Is this possible using RH9 or 7.3? Is there some software or method available in the GNU community that allows this?
My thinking is that I'd have to constantly place the content on CDs and upload the data from that.

TIA
