This bitmap value tracks which specific configuration attributes within an HTTP profile entry have been explicitly set by an administrator, as opposed to values that were only set implicitly as a side effect of configuring some other attribute in the same profile, and once a bit is explicitly set it can only be cleared by explicitly reconfiguring this map itself. An administrator generally doesn't set this directly during normal configuration, since it's mainly maintained automatically as a side effect of setting the profile's other attributes, but a management system might read it to determine precisely which fields in a profile were deliberately configured versus left at implicit defaults. For example, after an administrator explicitly sets juniHttpProfileRedirectUrl on a profile, the corresponding bit in this map for that attribute would automatically become set to reflect that it was explicitly configured.
