\&  modperl_request_output
\&  modperl_request_input

.Ve
.PP
You can see the names of the non\-mod_perl filters as well. By calling
\&\f(CW\*(C`$filter\->next\->frec\->name\*(C'\fR
you can get the name of the next filter in the chain.
.PP
Example:
.PP
Let's print the name of the current and the filter that follows it:
.PP
.Vb 5
\&  use Apache2::Filter ();
\&  use Apache2::FilterRec ();
\&  for my $frec ($filter\->frec, $filter\->next\->frec) {
\&      print "Name: ", $frec\->name;
