How to hook end of POST

[Kenji Tayama]

Hi,

I'm trying to hook the end of POST calls, and I've tried these :

Filter#afterHandle
Handler#handleXxx
Application#handle

Works fine for GET requests, but for POST requests, these get called before
response data is sent to the browser.

Is there any way to hook the point when response data is sent?

Thanks,
