how to receive POST data in handler (stub)

[Anatoli Marinov]

Hello colleagues,
I am wondering is it possible to receive whole post data in a handler 
module? If it possible where I can found the received post data.
I am writing a module that should be able to remove some files from 
proxy_cache but I want to remove a bundle of them. The list with files 
will be send through POST request.
Thanks in advance
