How to do file replication

I just configured mysql DB replication but I also need to do simple file replication (xml files).

For example I have a file:

relative path: some_folder/something.xml;
absolute path: /home/www/some_folder/something.xml;

By now I read file the most usual way with JSP. I need two things:

1. Every update - need to update the replicated file on slave machine. Also I create files, so I need to create them on slave machine as well every time it occurs.

2. Need to read/use it in the slave machine if the "master file" fails.

How can I accomplish that?
