directive;

-.B response-callback { head | tail }
-Specifies whether the response callback should be placed at the
-.B tail
-(the default) or at the
-.B head
-(actually, wherever the stacking sequence would make it appear)
-of the callback list. This affects how the overlay interacts with other
-overlays, since the proxycache overlay should be executed as early
-as possible (and thus configured as late as possible), to get
-a chance to return the cached results; however, if executed early
-at response, it would cache entries that may be later "massaged"
-by other databases and thus returned \fIafter\fP massaging the first
-time, and \fIbefore\fP massaging when cached.
