	PW-no-wpleak.so

   Usage:
   At the beginning of obj.conf:
      Init fn=load-modules shlib=PW_no_wpleak.so funcs="PW-no-wpleak"
   Inside an object in obj.conf (preferably at the top of the default object):
      PathCheck fn=PW-no-wpleak
   
   The PathCheck gives a 404 for any request containing known WebPublisher tags.
	(i.e. with a QUERY_STRING beginning with a known tag)
