Subject: [PATCH] Implements a virtual destructor on the BaseRequestHandler
 class.

Implements a virtual destructor on the BaseRequestHandler class to protect against undefined behavior in
the event that a derived BaseRequestHandler class has a destructor and an object of such derived class
is destroyed through a pointer to its base class.
