This is common in chaining and module cooperation because
$r->content is a one time event, as the content gets consumed
on the first read.  What you can do is use Apache::ASP first
and your module second, no prob, because in Apache::ASP, I cache
the input and retie STDIN, so other environments, like CGI
can be initialized without interfering.

So it should work the other way around at least. I might also 
try creating creating a subclass of the apache request object, 
and override content to make it reusable.  I don't even know if 
its possible, but its worth looking into.

This is a common problem to chaining, filtering, and using
different environments at the same time.  If you repost
this as a more generic mod_perl problem, you may get 
more diverse responses.
