Apache 1.x does not support this -- stdout is tied to the socket, iirc.  If 
you are into heavy wizardry, you might try redirecting the stdout file 
descriptor (fd 0) before the subrequest and restore it afterwards.  Note that 
this requires more than tieing STDOUT to something else and is likely to be OS 
dependent to some degree.

Apache 2.x has support for I/O layering which would (hopefully) provide for 
this.
