Related to that:

Actually I think we are going to need two filters on the request body:

* a VFP on the way into the cache (where we might want to use the request body
with vmods and/or VCL)

* a VDP when sending it to the backend.

As a concrete example, one might want to uncompress the request body for vmod
processing, but recompress it for delivery to the backend.

Preserving the original request body would be another complication...
