-=head3 Filtering by parameter location
-
-If you have different filters that depend on whether a param was passed
-as a query or body param (or as either), you can specify a hashref with
-different sets of filters:
-
- # filters all body parameters
- __PACKAGE__->config( Debug => { param_filters => { body => qr// } } );
+=head2 $c->log_response_headers($headers);
- # filters query parameters starting with 'private'.
- __PACKAGE__->config( Debug => { param_filters => { query => qr/^private\./ } } );
+Hook method which can be wrapped by plugins to log the responseheaders.
+No-op in the default implementation.
- # filters all parameters (query or body) through the specified callback
- __PACKAGE__->config(
- Debug => {
- param_filters => {
- all => sub { return unless $_[0] eq 'fizzbuzz'; return 'FIZZBUZZ FILTER' }
- }
- }
- );
+=cut
-Of course, you can use any of the above filtering methods with these
-"location-specific" filters:
-
- # body parameter filters
- __PACKAGE__->config(
- Debug => {
- param_filters => {
- body => [
- 'some_param',
- qr/^private\./,
- sub { return 'XXX' if shift eq 'other_param' }

- 'some_param',
- qr/^private\./,
- sub { return 'XXX' if shift eq 'other_param' }
- ]
- }
- }
- );
+=head2 $c->log_request_parameters( query => {}, body => {} )

-sensitive data to your logs (e.g. cookie values, etc.). The configuration
-works in virtually the same way as the examples in

-
