reading yet preserving request body

Hi folks,

I have an MVC-style system which passes the request object to various
modules until one of the 'accepts' it.

I'm using Apache2::Request to parse incoming form parameters which is fine.

The problem is that some of these modules want to read XML or Multipart
MIME from the request body, but of course Apache2::Request wants to read
it too. If I create my Apache2::Request object, then use $r->read() to
read the body, then call discard_request_body(), will I be able to have
my cake and eat it?

thanks
John
