What could be advantage of ServletRequestWrapper over Filter?

In this thread it was cleary stated why ServletResponseWrapper can be useful. What about ServletRequestWrapper? What real application may use a ServletRequestWrapper for if in fact all could be achieved with just a Filter? Can somebody provide a scenario?

The question is not to use an implementation Filter or a ServletRequestWrapper / ServletResponseWrapper . The answer that you linked in your question is good, but it doesn't point out an important fact: wrappers are often, or even mostly, created during the execution of the method doFilter() in a class which implements the interface Filter.

Take a careful look at the links which BalusC has posted in his comment.
