 /**
 26   
  * Local servlet request wrapper. The purpose of this wrapper is to hold
 27   
  * attribute information that is need for each request.  In a threaded environment,
 28   
  * each thread needs to have its own copy of this information so that there is
 29   
  * not a timing issue with the original request object.
 30   
  * Also, since the original request is no longer "holding" the attributes,
 31   
  * there is no reason to remove them in the finally block.
 32   
  * The LocalServletRequest object is automatically garbage collected at then
 33   
  * end of this method.
