-their values replaced with '[FILTERED]'. For instance:

+ $c->log_response_headers($response->headers);
+}
- [debug] Query Parameters are:
- .-------------------------------------+--------------------------------------.
- | Parameter | Value |
- +-------------------------------------+--------------------------------------+
- | password | [FILTERED] |
- .-------------------------------------+--------------------------------------.

-=head3 Filtering parameters by regular expression

-If you have a set of parameters you need to filter, you can specify a
-regular expression that will be used to match against parameter names.
+=over 4
- # filters parameters starting with "private."
- __PACKAGE__->config( Debug => { param_filters => qr/^private\./ } );
+=item * Response status code
- # filters parameters named "param1" or starting with "private." or "secret."
- __PACKAGE__->config( Debug => { param_filters => [ 'param1', qr/^private\./, qr/^secret\./ ] } );

-Notice on the second example, the arrayref contains a string as well
-as two regular expressions. This should DWIM and filter parameters that
-match any of the filters specified.

-=head3 Filtering parameters by callback
+=back
-If you want even more flexible filtering, you can specify an anonymous
-subroutine. The subroutine is given the parameter name and value and
-is expected to return the new value that will be shown in the debug log.
-An C<undef> return value indicates that no change should be made to
-the value.

-Writes HTTP::Headers to debug logs, applying filters as configured.
-
-Similarly to how L</log_request_parameters> is configured, you can
-configure Catalyst to filter response header values to avoid writing
-sensitive data to your logs (e.g. cookie values, etc.). The configuration
-works in virtually the same way as the examples in
-L</log_request_parameters>. Here are a few specific examples:
-
- # filters all "Set-Cookie" headers from response logging
- __PACKAGE__->config(Debug => { response_header_filters => 'Set-Cookie' } );
-
- # filters only the value of the cookie (and leaves the name, path, expiration)
- __PACKAGE__->config(
- Debug => {
- response_header_filters => sub {
- my ( $n, $v ) = @_;
- return unless $n eq 'Set-Cookie';
- $v =~ s/^.*?;//;
- return $v;
- },
- }
- );
+Logs L<HTTP::Headers> (either request or response) to the debug logs.
