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...
 
Don't get me started about those stupid light bulbs.
