Hi all, which three are true about the HttpServletRequestWrapper class?

A. The HttpServletRequestWrapper is an example of the Decorator pattern.
B. The HttpServletRequestWrapper can be used to extend the functionally of a servlet request.
C. A subclass of HttpServletRequestWrapper CANNOT modify the behavior of the getReader method.
D. An HttpServletRequestWrapper may be used only by a class implementing the javax.servlet.Filter interface.
E. An HttpServletRequestWrapper CANNOT be used on the request passed to the
RequestDispatcher.include method.
F. An HttpServletRequestWrapper may modify the header of a request within an object implementing the javax.servlet.Filter interface.

Is it ABF?

KD.
