|
|
=head2 handler ( request, server, config )
|
|
|
|
The Apache request handler for this package.
|
|
|
|
This handler takes care of certain special tokens returns by a sub-handler.
|
|
|
|
=head3 chunked
|
|
|
|
This indicates that the handler has already returned the output to Apache. Commonly
|
|
used in Assets to get head tags back to the user to speed up the rendering process.
|
|
|
|
=head3 empty
|
|
|
|
This token indicates that the asset is legitimatally empty. Returns nothing
|
|
to the user, instead of displaying the Page Not Found page.
