Internal redirect inside an input filter

[Dan DeSmet]

I'm attempting to write an input filter that performs an internal redirect
based on the contents of the cookies sent in the request headers.  The
problem I'm encountering is that the browser is receiving both the content
for the original request, as well as the content generated by the internal
redirect.  Ideally, the browser would receive only the content generated
from the internal redirect.  Here is a sample filter I wrote while trying to
solve this problem:

package Test::Redirect;

# a bunch of use statements

sub handler : FilterRequestHandler {

    my $f = shift;
    # this is just any old uri
    $f->r->internal_redirect('/reverse');
    return Apache2::Const::OK;
}

I've tried setting the filter's context to allow it to run only once, but if
I do that, it never completes the request.  Any ideas?

Thanks,
Dan
