/**
|
* 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.
