[users@httpd] How to force the apache transfer the data in chunked mode?

[Nicle Yang]

Hi all,
   The apache manual says:"If the client requests it, chunked encoding will be used in order to send content of unknown length over persistent connections.", but I wanna the apache transfer the data in chunked mode, even though we the length of the data. How can I configure it?

Best Regards
