Output transformers are applied just before output is sent to the browser. This directive adds a transformer to the list of transformers to be applied to the output.
AxAddOutputTransformer MyModule::Transformer
The transformer is a subroutine that accepts a line to process and returns the transformed line:
package MyModule; sub Transformer { my $line = shift; . . . return $line; }
You can use an output transformer to add dynamic output (such as the date and time or a customer name ) to a cached page.
