I have looked this up, but I cannot seem to understand a good use for it. What exactly does it do? What would be soem advantages to using it? Can I get a real world commitment.

The functionalities of the general HttpServletRequest or HttpServletResponse are limited. If you wanna a customized function, you must wrapper them.
e.g., if you wanna GZip the response message. You can create an instance of
a Wrapper response which includes the GZip compression feature. Afterwards, everything written into this wrapper is automatically Gzipped.
Hope it helps.

There was a discussion here a few days ago where the Request Wrapper seemed like a useful idea.

This approach is for instance used by the JSTL implementation of the import tag..
The tag does a .. include(request, ServletResponseWrapper ) instaed of the regular include(request, response).
The reason I guess is to better control the writing to the response object, and to have better control with the flushin of whatever is in the response object...
