As far as I know you can't do that, since mod_proxy doesn't cooperate 
with the backend.

Anybody knows of similar to mod_proxy modules that do play nicely with 
the backend regarding aborted connections?

I've never used it, but wasn't mod_backhand supposed to do this?

I think dapi said his mod_accel might do that, and wasn't mod_deflate
supposed to do something like that too?  Can't remember.
