   # the snooping debug filter). Of course if the filter returns
   # Apache::DECLINED the unconsumed data will be passed to upstream filter
   #
  +# However this filter has a problem. Since it doesn't consume all the
  +# data, the client is left with un-read data, and when the response is
  +# sent a client get the broken pipe on the socket. It seems that LWP
  +# on linux handles that situation gracefully, but not on win32, where
  +# it silently dies. Other clients may have similar problems as
  +# well. The proper solution is to consume all the data till EOS and
  +# just drop it on the floor if it's unneeded. Unfortunately we waste
  +# the resources of passing the data through all filters in the chain
  +# and doing a wasteful work, but currently there is no way to tell the
  +# in_core network filter to discard all the data without passing it
  +# upstream. Notice that in this test we solve the problem in a
  +# different manner, we simply call $r->discard_request_body which does
  +# the trick. However it's inappropriate for a stand-alone filter, who
  +# should read all the data in instead.
