What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']?

What’s the difference between $_SERVER[\'PATH_INFO\'] and $_SERVER[\'ORIG_PATH_INFO\']? How do I use them?

When I run print_r($_SERVE

Prior to 5.2.4, PATH_INFO was apparently broken (not set) in the default configuration. Perhaps that's it.

The PHP manual says that ORIG_PATH_INFO is:

Original version of 'PATH_INFO' before processed by PHP.
