That looks like my config ;-)
The point is, must I take care of the DAV specific things ?
For example, I wrote a sub named input (whoww!)
which did nothing more than consuming the input files on
PUT request, it should return to the upper/lower layers
afterwards. But the apache process which handled my request, hang.

sub input {
    my $req = shift;
    if($req->method eq "PUT") {
       #maybe nothing here allowed ?
    }
    return Apache::OK;
}

1;

Caused that effect. Am I thinking wrong ?

Mh, for streams with a token size of 32-64 bits, you could try

It's easy to implement in perl, as the C source is easy.

I use the C source to encrypt 64 bit tokens, which would
be 8 bytes from a stream.

Perhaps you can then tie that thing between your stream.
