This way the = configuration changes will be available for all nodes, without need for = synching any files. While this looks almost like a no-brainer, I am = wondering if there are any pitfalls I need to be aware of. On a related question, is there a best practices (do's and don'ts ) = document that you can suggest other than the regular documentation by = Apache? Thanks! -Mehmet=
