+/**
+ * ServletRequestWrapper is a pass-through/delegate wrapper class for a servlet
+ * request. This class is used in conjunction with ServletFilters, such as the
+ * AccessRestrictionFilter.
+ *
+ * The original request is wrapped by instances of this class and this class is
+ * set as the servlet request in the filter. This allows for specialized
+ * implementations of request methods, like getUserPrincipal() with delegation
+ * to the original request for any method not overridden.
+ *
+ * This class, by itself, is not altogether interesting. Subclasses of this
+ * class, however, are of interest.
