//normally in order to determine if a child is supposed to follow the parent
//one can use m_dwFlags & REDIR_FOLLOW_PARENT. However, this information
//gets lost when UpdateDescendant is invoked as it sets the redirection
//settings based on its parent. In fact, after this, if
//m_dwFlags & REDIR_FOLLOW_PARENT still succeeds, it is an indication of
//the fact that UpdateDescendant failed. Thus, in the redirection phase
//we need to keep track of whether a child was supposed to follow the parent
//or not so that redirection of a child is not attempted if that of the
//parent fails
//hence the following variable is used to keep track of whether a child
//was supposed to follow the parent or not
BOOL m_bFollowsParent;
//the following variable is used to keep track of whether redirection has
//already been attempted for this particular folder. This is necessary
//because redirection of special descendants may be attempted via their
//parents as well as via the normal iteration in ProcessGroupPolicy so
//we don't want to attempt the redirection twice
BOOL m_bRedirectionAttempted;
//also, we must record the return code whenever we attempt redirection
//so that we can record the same code when redirection is attempted again.
//this is necessary because when redirection of a special descendant folder
//is attempted via the parent, then this is the only place where its return
//value is recorded. When redirection of the special descendant is attempted
//again in the normal iteration in ProcessGroupPolicy, the Redirect member
//function returns the value stored in m_StatusRedirection which is then
//recorded by ProcessGroupPolicy and reported back to the policy engine
//this ensures that the wrong value is never recorded for any folder and
//that the policy engine never gets back an incorrect return value.
